Blitzheart's Lair

Follow the small stream into the dark, winding maze of the Tumbling Tunnels. Keep following the river, even as it stops flowing and freezes over. It'll get so cold there'll be ice sinking in between your scales, making it hard to move and harder to breathe - keep going. Eventually, the labyrinth of tunnels opens into a deep, frozen cavern. Massive spines of ice hang from the ceiling, and along the floor, frozen in huge crystals of it - there are dragons.
