Amsmark

Amsmark was a small town of which the location is now unknown. Some people say that it was located 956 kilometres north of where Unity currently is. The only proof of its existence was the large nuclear bunker near the town. However, all knowledge of its whereabouts got erased after The Decimation. Rumours go that the bunker still exists and survived the huge blastwave caused by Dremika.

History
Amsmark was previously a 132-man village, founded in 10BD, filled only with scientists. Although there was a small population, the area was huge and mostly contaminated with Tri-Unumic acid, also known as TUA-46. For unknown reasons the scientists had an immunity for this highly poisonous substance. Other people in this area either died of acute poisoning or developed a chronic blood disorder called Unuminosis.

In 4BD, the group started the construction of a nuclear weapon, called Nuclear Messiah to destroy Dremika. Although at first everthing went alright, upon activation, the weapon caused a Severe Causality Meltdown due to the amount of energy and the bend of spacetime. This caused all energy in the weapon to be turned into pure heat, light and radiation. The ensueing explosion killed every single person in a radius of 200km to die, either of heat or radiation. The TUA-46 molecules all broke into Water and Ununium. Due to the instability of Ununium when unbound, a massive explosion further cleared the area in a radius of 600km.

Because Amsmark(due to the TUA-46 contamination) was a reasonably remote town with no other cities in a radius of 704 km, only an estimated 500 people died. After a suprisingly low half-life time of the radioactive atoms, the area was once again habitable. This didn't take long though, as in 1 BD the site was home to the Bloodbath of Amsmark.

Contamination
The cause of the TUA-46 contamination is unknown, but it is said that a missile containing this poison once fell down here. The cause of the immunity is even more mysterious, but it's possibly that it's simply because the scientists had an antipoison. No further documentation about this could be found.
