Gyrig was part of an expedition lead by Gerdain Ironjaw that had set off from Eye Bay just a few days ago to go and find the Temple of Mortus. His expedition wasn't a lucky one. His recollection of the last few days is foggy as he is delirious and doesn't remember much besides having set up camp recently and then just fear he can't explain. He ran away and stumbled around strange tunnels for who knows how long and ended up in this cave just now.
