This role is played by the moderator: in mod-host and in-person games the mod messages the player in private chat and resolves the ability by hand. Automated nights do not prompt for it.
Each night, along with the other wolves, choose a player to eliminate. The first night, choose a player to be your owner. If you are eliminated before they are, they recognize you and are eliminated as well.
Wins when
Wins with the wolves once they outnumber the village.
What you'll see at night
No night prompts. The moderator runs this role in private chat.
Variants
Pet Wolf
Kills with the pack. On the first night, choose an owner; if you die before them, they're eliminated too.
Mod-run via private chat. Prompts and messages are generated by the same night engine the game runs, so they match what players see.
