Bound in the Frostfell, Dral Khatuur embodies all of the
terrors of winter—endless night, the killing frost, the ice-encrusted face of a frozen friend. Her minions are frozen
corpses, fiends sculpted from ice, and the howling,
hungry wind. She despises all other creatures, including
the other overlords; she has no ties to the Lords of Dust,
and waits in the Frostfell for anyone foolish enough to
venture into her domain.
