Anyway to get the key to that room you need to mindread one of the bandits which is only possible if you choose to go to the bandit camp before you go back to tell Lt Louis the location.
Ragnar = 400 exp = Learn the location of the key to the gate holding treasure in the Temple of Doom.
if you go back to the shrine were you entered the tower area of broken vally, cross the bridge & you should see thee teleport neer the edge of the cliff next to the tower.
