The mafia games are completely inactive now. With that said, I would suggest changing the name of this role: https://www.voidcentury.club/memberlist.php?mode=group&g=30 to Game Manager. This way the role will apply to the leaders of Mafia and roleplaying games.
Change the banner character to someone else? (I think Kaido might be a good fit, lol)
Change the usergroup colour?
