If the Summoner is in play, the Clockmaker does not receive their information until a Demon is created.
The Summoner cannot create an in-play Demon. If the Summoner creates a not-in-play Demon, deaths tonight are arbitrary.
The Summoner may choose a player to become the Pukka on the 2nd night.
If the Summoner creates Legion, most players (including all evil players) become evil Legion.
If the game ends due to the Klutz's ability and no other characters were eliminated: eliminate the Klutz.
If Legion is the last character to die due to execution in a game, and loses as a result: Legion is eliminated.
