Fair enough. I wanted to make sure that I didn't miss an important plot arc. I was hoping it was the hero from Geneforge 4, since the ending of that installament was the least conclusive of the series IMHO.
I just finished the entire Geneforge series. One mystery remains: what was the background of the hero from Geneforge 5? Who/what was he before Rawal embedded a control creature into his chest?
