Hello Skia and welcome ^^ I am Lindsey ( Momma Linseh! With a smiley face ) I hope you enjoy your time on Avatar RPG
To answer your question about having a Dragon being a pet. Well it isn't in the rules that you cannot be a dragon or someone's pet. However i will ask that you figure out who will be your owner before you make the character. This would have to be okay with them, is what im saying.
Also, you do realize this means you will have to be with your owner in most topics, unless stated you are staying at home or what not.
Finally, since this has never really been before, i ask that you use the Original Character template, not the pet creation one. And be rather detailed about your dragons as in its history and what not. As dragons are rather powerfull beings please be aware of Godmodding and power play. He cannot be too powerfull.
Other than that, Do you have anymore questions? I would be glad to answer any of them for you.
Your lovely admin ~ Mommy Lindsey ^^
