Yes, it is an L shape, but there is a small problem with that:

I'm shocked!...
How small is the stalactite, now. Basing on the above scetch, it looks like our real 1km isn't equal to PS km. Why?
From the book in library, we know the distance from inner to outer circumference is approx 9,7km. Looking at the picture, I gues the distance from Ojaveda to Hydlaa is like 15km. Do you think it is really that far in-game? ;P I think these 2 maps in beatwen are like 4 km or, so we have 6km max i gues.
There are two options.
a) 1 real km = 2,5 ps km. (what i refuse to accept ;P)
b) maps will be bigger in future and the distance will grow so that ps and real km will be equal.
Now you can call me math freak ;>
