We're in business. Better not betray me now.
There are 3 main factions not including the indies: Blue Dragon, Unseen, and Cult. Unseen/Cult are the two scum teams. Only one can exist at the same time. They function like a cultafia with a lean towards the cult side. Each Blue Dragon role in the game has its own Unseen/Cult version. Blue Dragon is basically town. If Unseen is present then a Sheriff is a must for the Blue Dragon. Likewise, if Cult is present, Paladin is a must. There can't be a Paladin in an Unseen game or a Sheriff in a Cult game. If neither exists then it's Blue Dragon vs Indies.
There's the King, your role. The King can either be good or evil. This is determined through a coin flip. If the King dies, a new King can be elected. There are royalty roles that gain a buff in terms of votes for them in an election. The lynch is majority and similar to ToS, there's a trial once the lynch is capped. There are two phases in the trial. Discussion and voting. Discussion is when everyone can talk about the player being lynched and voting is when we all vote and only the King can talk.
That's the main gist of ToL. All other intricacies of the mechanics are in the guide. All the roles can be founded there too.
