if i made up a mythical creature called a Zealen would i be stealing someone elses name?

That's a very good question! あなた need to cover your back when 書く a story! I'm sorry I don't know the answer, I just wanted to say I hope no one has it, 'cause it's a really cool name for a mythical creature! Good luck to you☺♥

Don't think so. Look it up on Google and if it comes up as someone else's idea then make up something else..

yeah in the austin and ally show
