During this time, he taught a young Corun about Tiresian culture and technology. The Spherisian Corun remembered Sorcen fondly as not being an evil being but a person that simply served an evil empire. One day, Spheris came under attack from the Invid and Sorcen quickly took Corun to safety. As the attack came, Sorcen threw the young Spherisian to another servant to save him when an energy blast struck thus killing the Tirolian. Corun would always be thankful to Sorcen for his sacrifice and used him as an example of the fact that not all aliens were evil. The Spherisian would later tell the tale of Sorcen to his son, Beryl.
