- "If they fail in the battlefield, they will shame Astapor."
- ―Greizhen mo Ullhor on selling half-trained Unsullied
Greizhen accompanies fellow Good Master Kraznys mo Nakloz and a third Good Master for negotiations with Daenerys Targaryen and is amused by Kraznys' comments about her. When Daenerys states that she wants to buy not just the fully-trained Unsullied but the slaves in training as well, Greizhen opposes, concerned that if these half-trained warriors fail on the battlefield it would shame Astapor.
Greizhen is present at one of Astapor's plazas for the conclusion of the transaction with Daenerys: the Unsullied and the half-trained boys in exchange for her dragon Drogon. He is killed when Daenerys orders to Unsullied to kill all the Good Masters, slave-drivers and soldiers in the city, sparing only the children, and liberate all the slaves.

In the booksEdit
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.
