Once upon a time there was a man called George Ziets. He worked at Obsidian on Neverwinter Nights 2 and the Mask of the Betrayer <s>expansion</s> mod. He left to join Bethesda. I guess he didn't like the decor or something because as soon as he got there, he turned around and went right back to Obsidian, from the words of Sawyer:
George was at Bethesda for all of about five months. The Alex Brandon who left was the Audio dude.
