You know the rules to roleplays. They're very basic. Easiest info is make sure you talk in 3rd person, don't use asterisks, don't be a dick, don't use text speech in chats unless you're out of character.

You can play canon characters or make an OC, though if you make an OC, I hope you think very carefully about it.

There will be only one summoner and that will be me, because no offense but MINNNNNNNNEEEE.
