Honorary Guest
From the game's encyclopedia
A Feast can have an Honorary Guest, in whose honor the celebration is held. The central part of the banquet, the toast, will grant them Prestige due to this prominent position. But beware — it can also be a trap... Murder Feast hosts have a tendency for killing their Honorary Guest.
