It's always best to start at the beginning, so I'm starting this with title decisions!

What NOT to do:
Something that irks me is when I ask someone "Why is _____ the title of your story?" And they say "Because it sounds awesome!" (Or something along those lines) Titles are NOT chosen because they sound cool. This goes for more then just Warrior stories, but,still, I had to include it! You should always make sure your title relates to your story.

What you SHOULD do:
When coming up with a title, it's very important to make sure it actually fits the storyline. I always write down notes for my stories such as warrior names that I will give apprentices, the main character, the prophecy(if there is one), important quotes, or highlight events. The best thing to do is make these and then come up with a title. The best thing about Warrior Cat Fanfictions is that you already have one part set out for you: Warriors. Also, you have a sort of blueprint if you are doing a super edition title. If you are doing a 'Super Edition' title, then take your main character's name(let's say... Flowerstar) and make it Flowerstar's _____. The hard part is the second part. Let's say that in this story, Flowerstar is a cat who rules over her clan and stuff; we could call it Flowerstar's Reign. (Bad example) Terrible example, actually, but I hope this helped! If you AREN'T doing a super edition name, it's a bit more difficult. Try looking back on those highlight quotes, or maybe just the basic plot line, or the clan your story takes place in. Another bad example is coming(you've been warned):

If you look back on quotes: Quote: "You must abandon your past, for you cannot change that. You can only change the future. You could title your story Abandoned Past or Changing Future. You see?

If you look back on Highlight Events/Plotline: (now, it's time for a cliché!) Your living cat falls in love with a dark forest cat, and you could call this story Dark Love or something.

If you look at your Clan: (for this one, you might want to combine the other methods) Clan: ShadowClan
Because of an idea I'm going on in my head, I could call this book Darkened Path. I hope this helps!

Good Examples
(These are already on Wattpad, so don't think about taking them)
• Cavern of Shadows
• Tunnelwhisker's Battle WhimsicalWoods72
• Bloodscar's Rise
• Curled Silence MysteriousCurl Brambleclaw4Ever
• Prophecy of the Setting Sun Tigerheart
• Icetail's Enemy LightningStrikeTC

Bad Examples
(These aren't necessarily going to be bad, just imagine that despite how cool they sound, they don't relate to your story!)
• The Falling Star
• Night Echoes
Etc.

Ask any questions if there is something I didn't clear up!
