Dayspring Canyon

It's an unmarked location found northwest of Stendarr's Beacon. It appears as a small opening in the side of the mountain.

Geographic features
Within the canyon, the initial path lies within a narrow ravine that leads straight towards a breathtaking view of a glacial waterfall overlooking a large lake. By the lake are some remnants of a fisherman's camp among several samples of Spiky Grass found by the shore. The path on the left leads up a hill to Fort Dawnguard.

Dawnguard
A young Nord recruit named Agmaer can be found admiring the view. He asks if he can accompany the Dragonborn to the Fort and remarks on his nervous disposition and his high hopes of joining the Dawnguard.

Characters
Four refugees can be found outside the fort in a small camp.

Trivia
