Ridiculous ideas that may or may not work.
CONSPIRACY
So there's this variant on Mafia called "Conspiracy," where basically either no players are evil, or *every* player is evil except for one. Good players vote to decide if they think there's an evil team: if they're right, they win. If they wrongly say "no," the evil team wins, so I have been trying to work out if I can translate that into Clocktower.
Legion is the only demon. On paper this means that the good team could theoretically win by doing nothing and just letting the storyteller kill off Legion - if so, you should not play along. I would recommend you publicly declare that if no good players voted in a day, Legion kills a good player that night.
The other option is that this is an Atheist game, and there is no Legion. In this situation, the storyteller should be trying to simulate a Legion game, with no funny business! It will probably work best if some players register as good and others register as evil to abilities like the Village Idiot: you can kill the "evil" ones off at night.
A secret third option, which does not simulate Conspiracy but *is* a bit of fun, is to put a Summoner in-play and just have a couple of Minions roaming around for a day or two.
This is a very complicated script idea and might be too cursed to work, but I am having fun developing it. I will add further notes in due course!
