The Frost Gate (building)

The Frost Gate is a giant gate at the end of the passage that goes through the Northern Shiverpeaks and connects Ascalon to Kryta. The treacherous passage begins at Yak's Bend, goes through Borlis Pass and Grooble's Gulch, and ends at the The Frost Gate. After going through the gate, travelers find themselves at Beacon's Perch, the last Dwarven outpost before Kryta.

Opening the Frost Gate through its three mechanisms (attached to the chains in the picture) is the final objective of the Frost Gate mission.
