(Three Days Ago: Titan, Saturnian Orbital Area)

A tall pale looking woman was still guarding the enormously long blue object. She was worried if anyone or her husband would take it from her since she was a keeper of this mysterious Forerunner technology. Without her knowledge, a radiant blue portal flashed on the Halo ring. The Librarian was surprised to see who had come to meet her. The light from the portal appeared to be two purple skinned men. The younger one remained beside the Halo ring when his ancestor walked over and confronted the lady Forerunner. She was apprehensive to see the Mad Titan and his descendant who unexpectedly entered her lair.

" Thanos, Septimus, what are you doing here? " she asked.

" Well, I have some business to do which my descendant and his friends asked me to check on you, " he evilly grinned and replied.

" What do you want? "

" Just to have a chat with you, First-Light-Weaves-Living-Son, " Thanos answered and shrugged. " I just want to know how the things are going in this timeline. You know, I used to be born and live here, before I made such conquests and disasters. What a coincidence that you also live here. "

" You have taken the lives here in Titan, Thanos. I will not forgive you for such horror you made to your people. "

" For me, it's not horror. It's a very important and memorable accomplishment I have made, my lady. "

" You are already deceased, Thanos, " the Librarian sternly said. " You cannot alter our ages. Centuries ago, you have fulfilled your mission as a destroyer of worlds. Your descendant is continuing your terror along with the Covenant. "

" You mean, that boy? " he chuckled. " Ah, yes, he has already explained that to me before I reached here. "

" I will repeat the same question to make myself clear, " she stressed her words. " What do you want? "

" All I ever wanted is to bring death and disaster to humanity like what I am seeing right now, " he instantly answered and walked around in circles. " I have just come from the past to correct the balance of the universe by destroying it. I'm sure your husband has been glad for what I have done to the humanity which I am destined to do. "

" How did you know my husband? Tell me, " the Librarian nervously gulped and asked.

" I just have a talk with him before I invaded another planet from my timeline, " the Mad Titan said and intently looked at her. " The Didact has told me about humans who are the foolish creatures in this entire universe. That's why I have to the job to eliminate them including the other races who dared to oppose me! "

The lady Forerunner was more terrified than ever when she heard the Mad Titan's ultimate goal. She thought of protecting the Composer and taking it away from these two intruders, however she couldn't do anything at this moment. Septimus rolled his eyes and became more impatient which he wanted to do some action. He never wanted to wait further for his ancestor's instructions. Thanos curiously looked at the tall bright blue object and evilly grinned.

" My, what's this?! " he asked and laughed.

" Don't you dare to touch that, Thanos! " she angrily warned. " I won't let putting your hands with the Composer. "

" The Composer, then. So, this is what you called. "

The Librarian was about to illuminate her both hands, but she was being hindered by the younger Mad Titan using his Time Stone. She got froze as Septimus evilly smirked at her.

" Let me go! Let me go! " she yelled.

" You claim to be the wisest and most powerful woman in the universe. Yet, you are also foolish like anyone else! " Thanos darkly chuckled and used his Power Stone to carry the Composer with him.

" NO!! "

" You are not even worthy of keeping this thing. "

" The Composer will be brought to the Covenant for safekeeping and they will deliver it to your husband! " Septimus added.

" Don't you dare!! "

" Septimus, make her to shut up for once, " Thanos ordered. " I can't tolerate this wretched woman, anymore. "

" My pleasure, O great ancestor! " the young Mad Titan bowed and then looked at the Forerunner.

The Librarian was becoming more terrified than ever when she saw Septimus illuminating his Reality Stone in bright red light. He was ready to take down an ancient being's live, but he decided to distort her first. She readied herself to defend and retaliate in order to bring back that important object. Suddenly, she felt her body being twisted out of proportion. The Librarian was yelling in tremendous pain for the first time when she couldn't break free and find herself into normality. Septimus was loudly laughing when his ancestor evilly grinned and watched her in suffering as a form of entertainment.

" Now, take the Composer to your friends' place. They can tell us what to do with, " Thanos ordered his descendant.

" It's my pleasure, " the younger one replied and used his Space Stone to teleport the object away from this place.

The two Mad Titans immediately headed to the blue portal, leaving the Librarian in her distorted and warped in appearance. She was so unfortunate to face her encounter with them.

" I have to ask someone for help. I cannot do anything for this terrible situation, " she sadly thought. " Perhaps, Starlord and his lot could do something. "

(Covenant Holy City, High Charity
Ninth Age of Reclamation)

The bright blue portal from the Space Stone had appeared infront of the worm looking prophet dressed in red tunic who got curious of what was happening. From the radiant tunnel, Thanos and his descendant appeared and carried a sapphire looking object. The Prophet of Truth was surprised seeing what they had brought.

" Greetings, Great Prophet, " Septimus introduced. " My ancestor and I had visited the Forerunner's place and given you an offering. "

" What is that? " Truth asked.

" The Composer, " Thanos responded and placed the object near to the prophet.  " Now, tell us. What does it do? "

Truth closely looked and inspected it. He scratched his chin using his right hand and touched the object with his left. The two Mad Titans waited for him to respond.

" Why is he taking so long? " Septimus impatiently asked. " I don't want to wait anymore. "

" Relax, Septimus, " Thanos lowly spoke and gently patted his youngster's back. " He's taking more time to have a look. "

" I hope he's not stalling around. "

" How remarkable, " Truth commented in awe. " You have brought a very beautiful and amazing treasure from the Forerunner herself!  You two have done a good job from stealing it! "

" Now, tell us. What does it do? "

" The Composer was intended to bridge the physical and digital realms, thereby making the Forerunners immortal. However, the device was flawed: the process was not only extremely painful but irreversible, meaning the stored personalities could never be returned to biological form. Rather, it's going to be in virtual which the humans called. "

Thanos grinned and understood what the Covenant leader had explained. It was a perfect spot on that his mission from Titan was worthy. He knew it was not a mistake to visit the Librarian and steal the sacred object from her.

" So, that means a being could live forever and cannot experience death for a long time. "

" Exactly, " the prophet in red tunic nodded. " But you cannot function physically. "

" Hmph, how pathetic is that, " Septimus commented and crossed his both arms when he heard the prophet's answer and found it ridiculous. " How can you live and work using the ability of immortality?! You are merely living like a ghost! It doesn't make sense at all, Truth! "

" That is the reason why the Composer is created by one of the Forerunners, " Truth continued. " However, we will take this to the Didact himself, since he deserves to own this object for his benefit. Or perhaps, we can make it as an important weapon to wipe out all these delinquent humans for good! How does that it sound? "

" I see. That's more interesting, then, " Thanos grinned and understood what the prophet said. " Then, what are we going to do? "

" We shall plan to meet the Didact and give it to him. But before that, we will study the potential benefits of this object. It will take time to uncover its other function. "

" I might help you as well. "

" But what about those meddling humans? " Septimus asked and shrugged. " They might be after this sacred object and return to the Librarian. We cannot allow that to happen! We must do something, Truth! "

" Patience, Septimus, " he calmly replied.  " Together, we can secure this Forerunner device and defend our premises.  That's why I ask you and your ancestor to do the job. Understood? "

" Yes, Truth. "

" We can handle them, Septimus, " Thanos assured. " We will make sure we will not fail on this before I return to my timeline. "

" So, that great lady in the sky just communicated you for an important mission, " Rocket said when he heard the story from his teammate.

" Well, yeah, " Quill nodded. " Honestly, I don't know what that tall bright bluey thing is, but it's a very important object for her. "

" You mean a Forerunner device? " Chris Halsey raised his voice and snapped his finger.

" Yeah, I don't know what it's called, " the scarlet-haired scratched his head and raised left hand in interjection. " But she said that Thanos and his kid stole it from her. "

" That ain't good, seriously, " Tengfei anxiously muttered.

" Damn..." Anna-26 exasperatedly sighed. 

" Now, how are we gonna find that bluish thing? " Drax asked.

" I don't know, Drax, " Quill raised his voice and shrugged. " Look, we faced the Gorilla guys along with the Zombies and the Spartans. We don't know where and who are they dealing with?! I have been kidnapped right?! "

" Chris, Anna, got any clues? " Gamora turned to the two UNSC Spartans.

" Hmmm, " the Spartan-II scratched his chin as the female AI's voice called his attention by giving him a loud beep from his helmet. " Cortana, what is it? "

" Chris, I have a theory that the Covenant has been dealing with Septimus the Mad Titan, " Cortana answered.

" Good thinking, Cortana, " he nodded.

" I am Groot? " Groot curiously raised his voice as he was unfamiliar to those beings.

" Remember, the meeting earlier? " Tengfei reminded. " The humans and a rogue alien race were at war for more than five centuries. "

" So, the Covenant are the bad guys, right? " Mantis asked.

" Yeah, Septimus the Mad Titan is a direct descendant of the one whom we are despising right now. "

Gamora raised her eyebrows in shock as she couldn't realize that her despicable adoptive father had gained another offspring in this generation. The green skinned lady angrily clenched her both fists and thought of killing him for good. The red headed Terran looked at her with a concern and thought of talking to her in private. Gamora went away from the group as he followed her.

" Gamora? " Quill called his girlfriend's name. " Are you okay? "

" I don't like to hear this..." she seriously muttered. " We need to stop Thanos and his bastard in this timeline. "

" Woah, woah, woah, it's not that easy to do that in one snap. "

" Peter, if Thanos has a living descendant here, that means he's done it! "

" Gamora, it's not that easy to take down that evil grape ape, " he reasoned. " Even the Librarian has warned me of it! "

Gamora heavily sighed and crossed her both arms. She felt disappointed and heard her boyfriend's response. For her, she witnessed how her adoptive father created chaos to so many worlds he has been. Gamora wanted revenge and justice for the things he had done to those innocent people who perished.

" Look, Gamora, " he calmly spoke and held her both hands. " I know it's frustrating to hear what I have said. "

" So, what are we gonna do? Are we gonna watch him and his monster making all of these disasters? Peter, if only we can find a way to stop them, " she said. " I knew how terrible he did in our time. But in this future, they have done so much. I don't want to see anyone in bloodshed. We need to do something before it happens. "

" Gamora, remember the legend of the Infinity Stones which the Kree Captain had mentioned? You even told me about the stones and those people. They will give us hope. You even asked me to find them. Then, I asked you if they're just made-up, like fairy tales or legends. Then, you're not even sure of it. You told me if we can find them, we can ask for help. Now, we have asked for it through me and the Librarian herself. "

His green-skinned girlfriend remained silent and sadly bowed her head. Quill hugged and gently rubbed her back.

" Peter, I have no words to say..." she said. " I just really don't know what can we do to save the universe together. "

" The Great Miss Librarian once told me, ' You will help your people in this timeline. ' That's the only thing we can do for now, before that Grape Ape. I'm so sure we will find a way to meet those people with the Infinity Stones to defeat him. There's still hope. "

Gamora hugged him back and smiled when her boyfriend felt pleased. Suddenly, the Kree Spartan-IV lady noticed them and cleared her throat. They turned their attention to her and waited for her to speak.

" I'm sorry to bother your heartwarming moments, guys, " Anna-26 spoke. " Master Chief has called us to return to the UNSC Headquarters for further plans in attacking the Covenant. We need you guys, they might  be plotting something bad. "

" Thanks, Anna, " Quill smiled and nodded. " I guess we're back in business, then. You and Teng should take this ship and bust us out of here. Understood? "

" Yes, sir! " she smiled back and saluted him.
