The Guardian chooses their protected player(s) during the night, and they will be protected from attacks during the current night.
They may not protect the same player two days in a row, but may protect themself and/or alternate between two or more players.
Any attack against a player protected by the Guardian fails, however a protected player may still die through other means.
The Guardian is elected on the first full day with a living Mayor, a living Reporter and no living Guardian.
Protecting players from attacks is an immediate effect.
