Vulthuryol

Hidden Dragon summoned in the underground Dwarven city, Blackreach.

Summoning Vulkthuryol:

To summon Vulkthuryol, simply go to the center building area, where the big glowing orb is, and use Unrelenting Force on it. Doing so will make the orb ring, and echo throughout the caverns. This seems to piss off Vulkthuryol... Have fun.
