The remaining Trojans, mainly chieftains and warriors, about 12,000 in all with their clans, went north across the Black Sea into the Mare Moetis or "shallow sea" where the Don River ends (Caucasus region in southern Russia), and established a kingdom called Sicambria about 1150 BC.  The Romans would later refer to the inhabitants as Sicambrians.  The locals (nomadic Scythians) named these Trojan conquerors the "Iron people," or the Aes in their language.  The Aes (also As, Asa, Asas, Asen, Aesar, Aesir, Aesire, Ęsir or Asir) soon built their famous fortified city Aesgard or Asgard, described as "Troy in the north."  Various other sources collaborate this, stating the Trojans landed on the eastern shores with their superior weaponry, and claimed land.  The area became known as Asaland (Land of the Aesir) or Asaheim (Home of the Aesir).
