Greizhen mo Ullhor is a character in the third season. He is a slave-trader in the city of Astapor, on the coast of Slaver's Bay, and one of the Good Masters, the ruling elite of the city. He is an immensely wealthy individual who has grown rich from the training and trading of the Unsullied warrior-eunuchs.

In the books
In the A Song of Ice and Fire novels, when Daenerys meets with the Good Masters, one of them, Grazdan mo Ullhor, is hesitant to sell the half-trained Unsullied because if defeated Astapor and the Good Masters would be shamed. The name seems to have been changed because Grazdan is a common name in Slaver's Bay.
