Knowledge
Talibre's Door
Description
"The light will lead you to the truth."
A device of the Ancients shaped like a circle which makes a rather unpleasant sound when operational. Unlike its fancy name and description, it's rather plain to look at. It's clear that it leads to some place though.
Lafi Bedmountain and Martha Kiyen discovered it to be the entrance to Atoraxxion.
How to obtain
Can be obtained through [Atoraxxion: Vahmalkea Main Quest]
Perhaps you can find this by following the footsteps of the missing Martha Kiyen.
