ToME: the Tales of Maj'Eyal

Got this layout on Escape from Reknor (2), there was no enemies on the entire floor, and the entire level was visible on one screen.
I know that levels have quite a bit of spawn variance, but this seems a bit excessive.

Don't remember ever having cut off sections in Reknor, huh.

You can probably dig somewhere to access the rest of the level. The fact that there was no enemies is not THAT surprising, since they get tp away if they're too close to the stairs you come from.
