When this role is rolled, it is announced the beginning of D1 that the game is taking place in the Shadow Realm. In the Shadow Realm, when someone dies by a role's active ability, their killer gets their soul. When anyone collects at least three souls, the person with the souls wins, and everyone else loses, regardless of anyone's win conditions.
When someone is lynched you gain their obtained souls (but not their own soul), if any. When you are attacked, you are night immune as long as you have at least one soul, and you lose all your souls to protect yourself. The only way you can win is by collecting three souls. If you are attacked or the night ends when it is night three or greater, you gain a day vig shot. Just like any other killing abilities, you gain your victim's soul (but not their obtained souls).
If you die, the game leaves the shadow realm, all souls that are still in the game are converted to day vig shots, and the people those souls originally belonged to will be revived.
This role cannot be rerolled or removed from the rolelist after it is rolled.
