A Unknown who gambled too much and took too many drugs. Formerly affiliated with the raiders who stole Amber from Bethany Claie, back in the Old World. Rose made his life absolutely miserable, feeding his addictions and threatening him regularly. At one point, he squatted in Ahmad's stables outside of First Landing, and was out of money, on the brink of death from overdose and poison.
Seynomour wears a colourful feather cloak, and a pirate's hat with a plume in it.
Following the events of Amber's retrieval during and after Family Reunion, Seynomour was medically treated. He managed to sober up in the meantime, and as of Deus ex Machina, he is a captain of one of the Guild cutters that can be leased in First Landing Port. He still gambles, but knows moderation, and stays away from substances.
Seynomour speaks Tengu fluently, but his Common is very limited and rudimentary, often interspersed by gambling slang and jargon.
