The Thanatocracy of Ulvir

To satisfy my curiosity, I ordered the creature chained with links of silver so that we might converse, and demanded it tell me of its lord Ulvir.
"Don't be an ass," it said, in a voice as dry as bone. "Stake me, and let there be an end."
"You desire an end?" I asked, somewhat surprised.
"Yes," it replied.
"Why then do you serve him?"
"He feeds us," said the vampire. "Would you do the same?"
I shuddered. "Certainly not," I said.
Dead eyes glinted at me with, I believe, self-loathing. "We are welcome no place but in Ulvir," it said. "Despite our power, our choices are more constrained than yours. Slay me and have done."
And I could get nothing more.

History: The Dead One sits on the Throne of Skulls in the House of the Dead, there in the ancient city of Ulv. If anyone ever knew its gender, the memory is long since lost.

Does it matter? It certainly cannot breed. It has been dead for millennia. Dead, but still among the living.

It sits unmoving, a slumped corpse, shriveled and mummified. But though it is dead, it does not lack power. Its orders come into the thoughts of its terrified subordinates. Its powers motivate huge legions of undead warriors. It rules its domain with a bitter hand.

Its subjects it keeps in perpetual ignorance, their sole religion worship of their dead master. The slightest resistance to its rule is put down with the sword, the lash, and the stake. For a thousand years and more, it has ruled Ulvir.

But it could never conquer more; for beyond a certain distance from its throne, its undead legions collapsed into dust and rotting flesh.

That has changed, now. Magic is stronger. Death is on the march.

Death is Ulvir's friend. It revels in death. It plans to make the world its own.
