Haven't thought this through yet, but in medieval times, people did not sleep like us with LEDs everywhere. Not everyone slept at the same time, and sleep was divided into two phases or shifts, the first and second sleep. Monks had strange timings and woke up a couple of hours after midnight. People went on midnight patrols (maybe for werewolves). Also, it was common to sleep in the afternoon. For example, Forky would almost certainly have a siesta time after working with the cows and fields early in the morning. All these are for ROLE IDEAS. Look for things where the day night cycle shifts for the rest of the village. So here are some suggestions, some might work, some might not, but this is for the general direction in which to think rather than specific roles:
Soothsayer - can suddenly put the village to sleep in the middle of the day, during or before the voting phase
Monk - goes to sleep during the voting phase, and wakes up in the middle of the night. Cannot vote, can only think for the village, and cannot be killed by ww. Dies if all other villagers die.
Forager - Wakes up directly during the lynching phase :D Can only vote, cannot see what the rest of the village has talked about, then goes back to sleep.
Watchman - Can read what the wws are saying without the player names shown.
