El Fabuloso (Traitor Dandy) is the facet of El Fabuloso, the gnome banker and founder of the Boreal Bank, in his role as dandy and traitor.
At the Eiffel Tower Tournament he drank from the Cup of a Hundred Wishes and redirected the Gem of Creation to vault U-5-7-1 of the Mercane instead of founding Sigil. Seen from the public stage, the act was a betrayal of the Regulators. It was also the banking operation that closed his contract with the blue giants.
DreyFab records him as a “Wanderer prototype” who gave the gnome-Jewish lineage a bad name in Uchronic Paris. The Boreal Bank is a cross-gesta institution built on the betrayal, and the city was left incomplete after the maneuver.
