Amberikon (pronounced am-BEAR-ih-con) is a major city in western Viridia, located on the coast of the Sea of Ersas. Following the destruction of the Amberikon era clock in Y7550*, planar boundaries between the Material Plane and the Abyss intersected in eastern Thadria. This provided a means for creatures from either plane to pass into the other, something the demons of the Abyss began to do in significant numbers. The city of Amberikon and surrounding communities were quickly overrun before the demons began to appear elsewhere along the western coast of Thadria.
The city was entirely destroyed in the initial invasion, though the area was eventually re-secured after decades of fighting in the Amberikon Crusade. Though it took centuries for Amberikon to be re-established, today the community is a relatively small if thriving city. The modern city is located about five miles from the center of its old site, entirely rebuilt in the last thousand or so years. The church of Harinna holds great sway in Amberikon, and nearly all the city's inhabitants are devotees of the goddess.
