In ages past, when mankind as a whole did not journey to other continents, each region of the world had an associated domain in the Tempest. The Americas, particularly South America, had an underworld as rich and complex as that of the living. At the beginning of the 16th century, the empire seemed in ascendance as its ranks were flooded with the angry dead, prey to disease and war brought from Europe. The Third Great Maelstrom, which had just come to a close, left the Shadowlands relatively free from obstruction, and European Renegades revolting against Stygia fled en masse to the Dark Kingdom of Obsidian, only to discover that its afterlife was as enraged as its living counterpart was decimated. The resulting war saw great atrocities, the most significant of which involved causing the enemy capital city to be swallowed by a massive Nihil, drawing it into the Labyrinth. Though scattered pockets of the Obsidian Empire remain, the bulk of its wraiths were destroyed, leaving the territory vulnerable to invasion by Stygia.
