I get the impression that Saavedro didn't figure out the fourth symbol thing because he was so busy planning revenge in a fog of insanity he failed to internalize everything and/or consider other options. Perhaps Saavedro realized in this scene that his quest may have been unnecessary.

I wonder if, after this, Atrus has tried to reconnect with Saavedro and try to make up for his sons' actions...

I played this game, years ago,and I loved it

It bothers me that even after realizing that his people are alive, Saavedro still takes the opportunity to be vindictive towards Atrus and throw Raleeshahn into the abyss if you give him the opportunity to do so. You have to resort to tricking Saveedro and make him give up Raleeshahn in desperation. I know that he and the protagonist part ways on...well, I'll call them "cordial" terms, since he ultimately goes home, but it leaves a bad taste in my mouth.

This is AMAZING! I can finally win my game of Exile without just figuring things out. Thanks for making this :)
