The part I'm talking about seems to be in between the part we're first teleported up to, and the second part of Level One which will teleport over to later - e.g. the chamber with the Sentinel Stalks.
It looks like a lot of this area contains water flowing on the floor from pipes.
So, my question is - is any of this area reachable without cheating?
If not, is this another area we might gain access to in the Book II expansion?
Otherwise, it seems like BW put a lot of work into a good part of the map we can't even get to!
