After ascending a steep flight of winding stairs you find yourself high above the rest of the sanctuary and looking out over a massive valley separating some of the highest peaks in the Blue Ridge mountains. Then, after walking some way above sheer cliffs a wall looms and, through a pair of large oak doors, offers salvation from the fierce cold.
As the doors open you are greeted by a blast of warm air and, despite the harsh conditions outside, the interior apparently remains quite temperate. Now you find yourself standing a grand hall and, although it's clearly seen better days, various demigods mingle under its arches and between columns as their voices echo in the rafters above.
You find several passageways leading to other sections of the fortress.
