Explorers and traders who have visited the Egarian Dominion have noted that the extinct xenos species built massive cities formed of intricate, elaborate, and maddening mazes that were left behind when their builders mysteriously vanished. These massive, cyclopean edifices dominate most of the Egarian landscape; many are large enough to rival even the massive hives of Imperial worlds such as Necromunda and others. They rise high above the desert dunes and desiccated scrub, vast walls and towers covered in strange protrusions and riddled with countless passages and corridors.
The mazes seem to be organized without any logical reason behind them, but that has not stopped explorers and xenosarcheologists from making the attempt. In a somewhat futile attempt to comprehend the maze-cities, a few scholars have attempted to quantify and analyse their structure. Any attempts to map the cities have universally failed—no matter how detailed the augur arrays or how exacting the surveys, the maps generated inevitably do not match the maze city structure when used.
