Yeah, bitches. I got them top-tier maids. I got 'em all! (Well, the ones I know and remember, anyway.)
Floor 10(The Nexus Core/Throne Room): Nix Celestine(Original)(technically the Area Guardian of the Throne Room/Protector of Seat of the Last Warden, but is the de-facto leader/manager of the rest of the Guardians)
Treasury: Haven't decided yet but I'm thinking of including another Anime character that'd fit the bill. I keep thinking of putting Nami from One Piece here for some reason and giving her some interesting/joke powers to help her defend 'her' Treasures($0$) from possible invaders(Hah! As if anyone would ever manage to reach All4One's treasury!).
Of course, I'm open to suggestions.
Feel free to suggest more characters that you think would fit the role of a Guardian or NPCs and I'd try to include them if I can. Though I'll only take a couple suggestions at most as the roster is already quite stacked, I think. Too many crossovers or even OCs might ruin the story or create a mess. (Or maybe they won't. Who knows! I sure don't!)
