Please add a "Character bio" entry in the character info screen. Other players will be able to see this when examining your character.
There are a lot of players that RP. Whether they Light RP and just like to play in character or Heavy RP developing deep storylines with others, this will be a good way to give a brief backstory on your character similar to how the entries in the old PSone FF game manuals were.
