Erandur talks as we make our way through the snow. He says that it feels good to finally have a chance to help the townsfolk. He points at a tower on the hill and says that the people of Dawnstar call it the Tower of Dawn. The tower was deserted for a long time before the Nightcaller Temple was established inside and now the temple too had been abandoned for decades. Erandur finds the thought ironic and calls it a ruin within a ruin.
We enter and arrives at a room. There are still traces of the Nightcaller Temple, like the big Daedra craving on the wall. However there does not seem to be any way leading deeper into the temple.
