According to the Journal these Labyrinths were all eventually abandoned by the gods which led to a series of wars with different races trying to claim ownership over them, in an effort to take the relics they contained.
It wasn't too far-fetched to believe considering I had one of these relics in my posession. But after reading a quarter of the Journal, I had to wonder if half the things the sorcerer said were true.
Some of it was simply too unbelievable.
How did he amass so much knowledge in such a short time?
Most of the things he'd seen and done were beyond the capabilities of a mortal, sorcerer or not.
Perhaps something happened during his travels or the absence of his family as a child turned him into some sort of ruthless monster...but even that wouldn't explain half of the unbelievable things I had read.
