Vulthuryol

Vulthuryol is a hidden Dragon summoned in the underground Dwarven city of Blackreach.

Summoning Vulthuryol
To find Vulthuryol, access the center building area in Blackreach, where there is a large glowing orb above the Blackreach Debate Hall and the Hall of Rumination. The closest entrace/exit in Blackreach to this orb is the Great Lift at Mzinchaleft. The orb is visible upon entry. To summon Vulthuryol, simply go big glowing orb and use Unrelenting Force on it. Doing so will make the orb ring, and echo throughout the caverns. This will call Vuthuryol to attack you.
