The Chain is a script including only info-gathering townsfolk, leading to town easily forming trust circles. However, with a spy, mezepholes, and plenty of poisoning, evil can easily work their way in the confirmation chains.
It's also a relatively beginner-friendly custom, with the only odd roles being the cannibal, lycanthrope, and Lil' Monsta.
I'd love to have some feedback, as I'd like to try running it soon.
