I really love Kings with their own separate agendas. Here is a bunch of ones that could be put into the game:
Coward King: Current Neutral King, crowned from Alchemist.
Vengeful King: King with Scorned objectives. Crowned from Scorned, may not use Decide Fate on targets.
Foolish King: King with Fool objectives. Crowned from Fool.
(Name Needed): King with Inquisitor objectives. Crowned from Inquisitor.
Those would be nice basic neutral King classes, that would prevent Scorned/Fool from escaping their goal. It would be cool if you could start the game with one of these, since it would make King more interesting. I also have a few other ideas:
Paranoid King: Eliminate everybody with royal blood.
Merchant King: Stall the game until day 9. Based off this idea.
(name needed): Kill all starting magic users. Does not include non magic users converted into cult.
