A Dance with Dragons
Grazdan mo Eraz travels to Volantis to persuade the Triarchs to send their fleet against Daenerys Targaryen. His bribes and feasts are said to be lavish, he brought slave girls and boys trained in Yunkai in the way of the seven sighs to pleasure the ruling class of Volantis.

Quotes by Grazdan
I pride myself on my knowledge of the savage senseless west. And yet, why should we speak thus harshly to one another? It is true that you committed savageries in Astapor, but we Yunkai’i are a most forgiving people. Your quarrel is not with us, Your Grace. Why squander your strength against our mighty walls when you will need every man to regain your father’s throne in far Westeros? Yunkai wishes you only well in that endeavor, and to prove the truth of that, I have brought you a gift. Fifty thousand golden marks. Yours, as a gesture of friendship from the Wise Masters of Yunkai. Gold given freely is better than plunder bought with blood, surely? So I say to you, Daenerys Targaryen, take this chest, and go.—Grazdan, to Daenerys Targaryen
You shall rue this arrogance, whore. These little lizards will not keep you safe, I promise you. We will fill the air with arrows if they come within a league of Yunkai. Do you think it is so hard to kill a dragon?—Grazdan, to Daenerys Targaryen
