An old adventure tile board game from the 70's / 80's?

Question

The game starts with all of the tiles turned faced down. The tiles are tiles of the house and the dungeon and the graveyard, ect. There is also a chapel and and lair I think. In the chapel you have sanctuary (that may actually be the name of the game .... uh I can't remember)

Also everyone draws a monster card, that is the villian you serve if and when to are turned evil. One person starts the game as a henchman (evil) and the others start out as heroes. There is a object like a grail or something which everyone is looking for which when it is found you take it back to either the chapel or the lair depending on if you are a hero or a villian.

As you play you get switched back and forth between good and evil and the object (for some reason I think it's a grail or something) keeps getting stolen from the players by each other.

I wished I could remember the name of this game!

Answer 1

It sounds like youre talking about Thieves' World: Sanctuary.

My older siblings used to have it...hope thats it.
