Roxas leaving this RP hanging lost it it's story, a valueable NPC, and a unified organisation. All we are are just players. For instance Midori, your character lost Akemi to Roxas' absence, which was pretty important for your character.

The RP needs to be rewritten and taken up by someone else, or a new one just gets made. You can't finish a puzzle if one piece is not there, so you either build a new one, or rework to fill that gap.
