Prince Khaldon of the Royal House of Drasnia is the ambassador to Tolnedra at Tol Honeth. His mother and Silk's mother were fourth cousins.

It is not certain if they are verbally playing with each other or whether it is more serious -- the two liked to banter with each other.

Khaldon [...] eyed his rat-faced relative. "You're looking a bit seedy, old man," he noted. "The last time I saw you, you were dripping gold and jewels." "I'm in disguise, cousin," Silk said blandly. "You're not supposed to be able to recognize me."

"Ah," Khaldon said. He turned to the Emperor. "Please excuse our banter, your Majesty. Kheldar here and I have loathed each other since childhood."

Silk grinned. "It was hate at first sight," he agreed. "We absolutely detest each other."

Khaldon smiled briefly. "When we were children, they used to hide all the knives every time our families visited each other." -- The King of the Murgos
