How to participate in PF, part 1: Most people start out making a character illustration and tying that character to a faction.
Are there any limits to your character? Not really. Pornographic material is not allowed but just about anything else goes. Some of the more outlandish characters have been a sentient humanoid coffee mug, and a baseball player with a magic bat. And a regular school girl warped into fantasy land.
When you post it, be sure to add the faction tag and relevant chapter tag at the time of posting to the illustration.
Tags change throughout the event so please pay attention to your tag usage! If you post an illustration in chapter 1 then change its tag to chapter 2, that is considered cheating and frowned upon. Tags have set times that they are allowed to be used, and ArohaJ posts those times in JST. Please calculate the time each tag is valid according to your own time zone.
