Walk Through

In order to access the version of Mar'uun that is not destroyed you must complete the Portal Space Research quest. After you complete all 4 weeks and save Mar'uun, you can do the Portalspace Rifts Quest.

Talk to Marcus Manfried and he will direct you to Kaywin, who will give you a Rift Opening Device and Rift Closing Device.
Now start looking for a a Portalspace Rift, which appears on the floor as a little vent of colored gas. They are found all over Mar'uun, not just near the Test Portal area. They disappear after a short time (due to a decay timer) but always appear in the same places.
Some known places of specific rifts:
- Fire: At the portal drop into town, one is in the hallway in front of you, and one is behind the bar on your right.
- Frost: One is under the stairs in the portal space research area, and one is near Kaywin in the little nook across from the stabilizing machines.
- Acid: One is in the hallway near Kaywin, and one is behind the northern screen in the furnished room.
- Electricity: One is next to the exit portal near the entrance, one is in Mar'uun's main circle hall, at a bend to the left of the entrance hallway, and one is in the furnished room behind the southern screen.
When you see one stand near it and use the Rift Opening Device and you will be portaled into the elemental plane of whatever elemental rift you used.
When you land in a room use your Rift Closing Device to initiate a spawn of elemental creatures. Kill all of them and a Elemental Zenith will spawn. Kill it and you will be portaled back to Mar'uun.
Repeat the steps above for 3 more elements until you have done all four then talk to Marcus for your reward.
