: Have you ever read or heard about the full implications
: of time travel? If not, I suggest you do. The main
: part I'm getting at here is that if you go back in
: time and change something, the future will be horribly
: &@$*ed because of what you did. Now, the codex is the
: future. If Alric screwed with his destiny, then he
: will screw up the future, and everything will be
: screwed up.
Whoever wrote the Codex could obviously see into the future. But, which future? There are, for all practical purposes, an infinite number of possible futures which can come from any single point in time, each differing very slightly, but over a long series of points in time, with different things happening (an electron happens to be here instead of there, connecting this neural pathway instead of not and causing a string of thoughts leading to a decicion which otherwise wouldn't happen) at each one, you can end up with vastly different futures.
So, lets say whoever wrote the Codex could see *all* possible futures, and wrote the book to take into account alternate timelines due to time-traveling information. There is a stable form of time travel called a world loop, where actions in the future cause events in the past, which force the actions in the future to occur. With a time-travel method like the Codex, where only information from the future is going to the past (however it's done, I don't want to go into hypothetical details), ending up with a stable world loop in almost inevitable, it seems. Whoever wrote the Codex could take this into account, and write the Codex as it would be seen in the world loop in the first place.
So, for example, it could say "You will trip over a rope in Tandem and crack your skull on a rock," so you decide that you're never going to go to Tandem. Then, however, the Codex would have to read something like "You would trip over a rope in Tandem and crack your skull on a rock, but having read this, you will stay away from Tandem, and instead will die in a robbery just south of Madrigal." But because of this, you'll make sure to stay away from Madrigal! And so on. Eventually, with some much evasion of different things, you may forget that you were originally fated to trip and die in Tandem, thus you end up in Tandem anyway. The Codex would then tell this, that you will forget to stay away from Tandem, and you will forget anyway. You've now got a world loop.
In other words, the Codex takes into account the fact that certain people will read it (and react certain ways) in its predictions, so it's always accurate. It knew Soulblighter would find the Summoner, and thus predicted that the Summoner would ressurect the Myrkridia, which in turn is what made Soulblighter search for him in the first place.
