Stygia

Stygia is a northern Ultima dead world that used to be a Knight world. A daemonic incursion gutted the population, then the dead started getting up; Freeblade Madrigal, last of his house and last of the living, patrols the ruins to keep them buried and to watch for the daemons' return. This is not Stygies VIII, not forge-world Stygia XII, and not the Executioners' Stygia-Aquilon twins.
