One portal to the 3 mountain areas near the arcology. No, I haven’t mentioned where the portal to the arcology is located. The player characters will have to find it.

Each of these portals are near the mountains of a specific color.

So the portal near the gray mountains, has no need of a lever to take the group to the gray mountains as they are already there.

No precise map details as I intend on running these in game sessions.

Portal near the Yellow Mountains:

Portal near the Brown Mountains:

Note there doesn’t seem to be a portal out of the area.
