Skirnon Ryu

Skirnon Ryu is a pre-Mending planeswalker from Kamigawa specializing in pathomancy, emotion-based magic. In addition to emotional manipulation and amplification, Skirnon can summon constructs based on his own emotional state. He is most well known for creating the plane of Novea.

Novea
Around 500 pre-Mending, Skirnon planeswalked to a plane that appeared to be an infinite void. Disturbed by this, Skirnon attempted to create something, anything, and tapped into the explosive mana of the plane, creating what would become Novea's sun, and its avatar born of his emotions.

Over the next few years, Skirnon would further develop the plane, though its inhabitants quickly began to take the future of the plane in their own hands. Finally, around 450 pre-Mending, Skirnon attempted to destroy the plane and ultimately failed. He left Novea disgraced, and has yet to return.

Skirnon wandered the Multiverse for another fifty years before all traces of the planeswalker vanish. Where he went, and whether or not he survived the Mending, is unknown.
