Shadow Glyph takes place in a realm named Midgard, the lands surrounding the Mydarius Sea in the mountainous northern region of its continent.  The Dominion is ruled by a Triumvirate system, a blend of democratic and aristocratic politics.  As its name suggests, the realm is divided into three fiefs, each ruled by an Imperial Prince.  The Three Princes vote on matters of kingdom import, but manage their own lands for the most part.  In times of conflict, the Princes can opt to elect a High Prince who receives complete authority until the conflict is resolved.  The Three Princes rule from Athyns, Olympus, and Avernus and convene when needed in Galinor, the City of the Throne.
