Liz warned Mur not to cross the Lighthouse portal because there were mutations in the outer rim, and the portal led to the Loop, so at least the Loop must be in the Outer Rim. And it is in SNEE.
I don't think Liz knew for sure that the Lighthouse Portal would lead to the Outer Rim, but I
have been tossing around the possibility of the Loop being in the Outer Rim.
Possibly because of all the instability in the Core due to Mur's Karma Portals, Liz thought that the Lighthouse Portal would give off a "random jump" to its user?
But Mateusz said somewhere that subnet=core+outer rim, not?
(sorry, I didn't read all the discussion).
That's alright.
And if he has said that, it's not in the Wiki under "Forum Posts," as far as I'm aware.
I actually didn't think any part of the SubNet that we've been to was part of the Outer Rim because:
a) The Outer Rim isn't mapped, yet if it wasn't, how come
we were able to get there easily?
b) According to Liz, only mutations exist out there. If the Root was in the Outer Rim, why would Liz know for a
fact Mur couldn't come back from the Outer Rim?
Also he has stated that not all of SNEE is on one layer.
Well, that certainly confuses things further.
