So lets assume that the Highlander universe has a True Faith merit like the World of Darkness. Would an immortal with sufficient faith make the ground they walk on Holy Ground? What would happen if they fought someone? It's possible Holy Ground is cultural and Connors sword shattering in Highlander III was just a coincidence, still, it could be an issue. Darius hadn't fought in a long time after he hid himself away in the church. Could he have effectively fought even if he thought it was justified? Was he so close to Duncan in part to keep himself indirectly in The Game, knowing he couldn't fight himself?
