Amadacia

Amadacia is a fortress hive world located in the Lotharian Marches subsector of the Vlaktes Mare. A temperate, biologically diverse world of tough tundra and rocky scrubland, Amadacia was originally colonized in M36 by Saint Lothair after millennia of isolation from the Imperium. The Vlaktes Sector was originally centered around its capital world of Amadacia, and its subsector. The Chronicles state that when Saint Lothair came to Amadacia he built a vast palatial fastness whence he launched his conquest of the sector. Later dubbed the First Tower, the capital became the template for all of Amadacia's many fortress-hives.
