Ravenlos Cleric was a cleric Alexander encountered on the Island of Llewdor in King's Quest ZZT, he was guarding the path up to Manannan's House for Ravenlos. He is able to shoot arrows and cast the spell Cause Light Wounds.
When Alexander encounters him he is given the option of claiming he is a soldier of Ravenlos, or that he Alexander, son of King Graham, or telling the cleric that it isn't his business. The latter two options lead directly into the fight. The first option leads to the cleric asking for a password. Alex is given the options of saying he doesn't know, that he needs to think on it, or the option to start a fight. The first and last choice lead direction into a fight with the cleric. If Alexander chooses to think on it, he is given four options. He can admit he doesn't know, or make blind guesses all choices lead to battle.
