After another half day's journey, the group had arrived within less than two miles of the Glacial Fortress. Considering the risk of being exposed by getting any closer, Lancelot decided to halt their advance and led his companions to climb a nearby hill.
In the Temple of Moradin, he and Bruto had already seen this fortress, but the vision in the illusion approached from the sky, which was entirely different from the scene they were witnessing on the ground.
As a symbol of dominion over this plane, the Abyssal Lord's lair was located at the peak of the highest mountain. A terrifying force had cleaved the mountain in two, and the Glacial Fortress was 'wedged' between the split peaks. The main body of the fortress was a gigantic ice block with a radius of over two hundred feet, its base more than five hundred feet above the ground, looking from afar like a tooth clamped between two fingers.
