Exile's EndThe sequence of events before and during the game of Exile is rather complicated. Where do all the Linking Books come from? How do people get from X to Y, and why can't they get from X to W? In addressing this issue, I'm going to be giving massive spoilers for the game of Exile, so consider yourself warned.
After they left, did Saavedro get back and forth between J'nanin, Narayan, and Tomahna? Since we find the Tomahna Book behind the inner shield, why was he able to access it? And what was it doing there, if Tomahna was made so many years after Narayan?
Finally, why didn't Atrus come follow us or at least know where we were?
MANY YEARS AGO, Narayan.
1. The brothers, leaving the Narayan main settlement, take the gondola out to the "platform" which we visit at the end of the game. Saavedro follows them there. Presumably the outer shield was open, or the gondola couldn't get there.
At this point, Saavedro is stuck on J'nanin.
1. The Linking Books to the Lesson Ages and to Narayan are all locked up in puzzles, just as when you find them. Saavedro can't get back to Narayan until he solves the Lesson Ages, gets the proper symbols, and puts them in the Narayan Book's imaging device.
Saavedro is now stuck. He can go between J'nanin and Narayan and the Lesson Ages, where he can obtain food and water, but cannot get past the outer shield.
How Saavedro reaches Tomahna.
Ten years pass. Atrus stops on J'nanin to take a look around while he's doing concept research for Releeshahn. When he links away, his Linking Book will be left behind. That Linking Book must lead to Tomahna. Saavedro suddenly has a new option.
For reasons best known to himself, Saavedro doesn't run down to call on Atrus for help, nor does he go to Tomahna to ask for help. From his notes and general attitude, it's obvious ten years of brooding have made him somewhat irrational, and he seems to have concluded that since Atrus never checked on Narayan, he is either an accomplice to or doesn't care about his sons' crimes. (And it's true, in a sense--why were Sirrus and Achenar able to conquer, pillage, and ruin so many Ages without Atrus noticing? Did he ever go back to help the survivors?)
Saavedro's revenge is not so much to do violence on Atrus--because he could well have killed the whole family--but rather, he sets up an elaborate plot to make Atrus feel some of the same helplessness and fear as he did. Saavedro means at the end to confront Atrus on Narayan, force him to see how his sons ruined the world. A small part of Saavedro still hopes Atrus can resurrect Narayan and its people, which he believes are dead. But he has very little hope, since the boys backed out of just such a primise.
Saavedro sets up his revenge
1. While Atrus is writing Releeshahn, Saavedro is preparing his trap. First, as we learn from his journals, he changes the symbols discovered at the end of the Lesson Ages into something new--something that doesn't match the "lessons" as described in Atrus' journal.
1. The stage is now set. You arrive in Tomahna for a visit to your friends, evidently having found Atrus again by having used one of the Books he dropped into th Star Fissure.
2. Saavedro has the J'nanin Linking Book in hand. He then Links through the Tomahna book to arrive in Atrus' office.
3. He grabs Releeshahn and starts a fire.
4. He links away. The J'nanin book falls from his hand.
5. You leap for the J'nanin book. Out of the corner of your eye, the fire is coming towards it from the right. The book burns the instant you leave, so Atrus has no idea where you went (even though, obviously, he must have another J'nanin Book somewhere to have visited it).
1. He runs up into the tusk on J'nanin. For some reason (this is one of the few glitches) he can't see you through the glass window, even though you can see him. "Atrus, is that you?"
1. Saavedro comes out to greet Atrus, only to find you instead.
