It appears in the An Arabian Knight scenario of Saladin, where the player must get a soldier to the mosque in Cairo, so that the Egyptians will change their diplomatic stance with him to ally. The mosque is actually surrounded by walls and a gate, therefore the player's unit actually only need to get to the gate (where there is a Monk outside). The player does not need to kill the monk even if he tries to convert the unit of the player, as once the player becomes allied with the Egyptians again, the monk can provide healing for the player.
