Crystal gem that disappeared and just came back.

You felt so drained, but knew it would be a bad idea to retreat to your gem until you knew you were safe. And the only place you knew you would be safe is the temple. You kept going for hours, the temple and your friends the only thing keeping you going. Fighting those corrupt gems for about a century takes so much away from you, actually they did take someone away from you. (Y/g/f) (your gem friend), the only gem who stayed by your side through all of your struggles.

Finally you reach the gem and this little boy looks at you with a smile. You try to weakly smile back but it takes the last of your energy and you poof into your gem.
