From Ardrana

Zybourn is a retired fighter from Rabk who served in the White Army in the closing days of the Wars of Arin. He currently serves as Rabk's representative on the White Council, being the official holder of the title of Duke of Rabk. He was appointed to that position by Milvey Pallianor some thirty years ago, a decision to which some nobles of the region objected. They had felt that the title should by right go to Eisten Ellistor, the Earl of Ellimer, but Eisten himself demurred.

Zybourn was a PC played by David Wargo and is now an NPC.
