Ulror Raska's son was an Haloga warleader from the Halogaland district of Namdalen. Some time after the Reign of Krispos, he decided to take advantage of a civil war in the Empire of Videssos between two rival emperors to seize the island of Kalavria. While the drive was generally succesful (much of Kalavria was in Halogai hands) Ulror found himself under siege in the fortress of Sotevag by the Videssian general Kypros Zigabenos. With the fall of Sotevag, the other Halogai positions could fall.
