“…the mad artist Dworkin Barimen, that wild-eyed hunchback who had been a sorcerer, priest, or psychiatrist — the stories conflicted on this point — from some distant Shadow where Dad had saved him from a disastrous fate he had brought upon himself. The details were unknown, but he had always been a bit off his rocker since that time. Still, he was a great artist, and it was undeniable that he possessed some strange power. He had vanished ages ago, after creating the cards and tracing the Pattern in Amber. We had often speculated about him, but no one seemed to know his whereabouts. Perhaps Dad had done him in, to keep his secrets secret.” – Corwin
An odd figure no longer seen in Amber, not much is known about Dworkin beyond speculation and rumour.
It is said that he created the Pattern, and he drew the Unicorn Trumps which the royal family now use to stay in touch with one another. It is also said that Delwin, Fiona and Brand trained with him.
He was known for his short and unpredictable temper — even Oberon was careful not to anger him.
