Wanted to know if this was at all possible. I've been working on an age that has two instances. One is a current state, and the other is the past of the age. The basic idea is that it is a scientific hall, where its inhabitants were experimenting with time travel. When the experiment went cacca, it destroyed the building, leaving it in its current state, but created vortexes inside of the temple in various rooms, connecting the past with the present.
The idea being that the only way to go deeper into the temple till you reach the end, where the experiment took place and the "time machine"rests, is to travel between the two instances, as the present temple, rubble blocks your advancement, and in the past rooms are closed off by doors.
My question is it possible to create link regions, similar to the PoTS route to Myst, where you step into the region, and are linked to another part of the same temple, or the second instance.
