A competent (mostly) version of Merlin from the Uber-Verse which is a more powerful alternate Amber chord.

Merlin sat on the throne of that Chaos, with an ultra-powerful artifact at his disposal: a staff that possessed an entire Logrus, Pattern, and major aspects of Trump within it.

He also had a pattern-based hammer that, somehow was also sharp, called Mjolnir. It was later appropriated by Oberon.

Upon request from Rainbow, Merlin came over to Amber Local in order to help Rainbow deal with Toram, who at this point was a slow-moving shadow.
