Mafia 90. The Tale of Oldforest.

Also, I really don't like Yashur, who cast his vote when it was already clear that the Warlock was going to be eliminated.

Why does everyone think that? Yashur's vote was the ninth, and it takes 9 votes to execute (17 players). This doesn't take into account possible Priest or Mermaid roles, but there was no information about them, so we can't say for sure that the Warlock would have been eliminated.

Therefore, executing the Heroist will be interesting if there were two Mafia members in the village.

Apparently, something else is interesting - on the first day, there were 2 polls, and both of them seem to have targeted villagers, and in both, judging by the poll, there were more Mafia roles :D
