Remember that PMs have history. If you join a PM, you will be able to see all of the history.
When you die, become a spectator and have an NPC take your place. The NPC does completely random actions, and you can use actions on them.
You can use 2 actions on an NPC, Guide and Remind. Each NPC, based on how long the player was in the game and what actions they took, has a specific, mostly randomly generated, Memory stat, which dictates how many Remind actions must be used to regain their memories (bring the person back into the game from spectator). They can then see all of the actions their NPC did, which were previously hidden.
Guiding an NPC will give them a point in your favor, at the end of the day or night, each NPC with an applicable vote (for exe or if night, NK) will vote with whoever guided them the most. Upon death, alignment will be revealed. When Guiding, you may input the name of whoever you wish to the NPC to vote for, Guide and Remind may only be used once each every day and every night.
Boom, Returned.
