I'm surprised no one has asked this yet on the forums but, maybe the
Sealed Pyramid in 600 A.D. in the pre-release was the dungeon found
in the game's code? If you use the code to acess it, you'll find it is fully
walkable and has exits on doors (i'm 99% sure it is anyway). Anyways,
what was the pyramid in 600 A.D. for? It was already open in 1000 A.D.
so why bother having it opened twice.
The events in the final version of the game seems to be something that
would only happen once if you know what I mean, so why have it
acessible twice
