If you do not have the Naakual crests required to use the crystals, you'll have to take the long route, traversing all of Outer Ra'Kaznar and Ra'Kaznar Inner Court.
You will have to pass through two Colonization Reives in Outer Ra'Kaznar, and two Colonization Reives in Ra'Kaznar Inner Court to get to Ra'Kaznar Turris.
You appear on a new map in Cirdas Caverns. Head to the northern room (H-6) and examine the ??? target on the crystal and choose to beam up.
You now appear in a deserted portion of Ra'Kaznar Inner Court. Head to the central room and examine the Vertical Transit Device to enter Ra'Kaznar Turris. Make sure to register the homepoint crystal next to the entrance.
Head down the ramps and you will end up at a target called Ominous Postern. Examine it for a cutscene that ejects you to Kamihr Drifts and completes the mission.
