I'm going to preface this by stating that what follows is a raid spoiler. I know you say the thread will be spoilery anyway, but this is stuff that isn't supposed to be known and has only be found through glitching into the raid. [spoiler]I can confirm that Clarity Control is in the raid, as an area in which there is a Veil statue like the ones found previously. In the video I saw they didn't take a closer look at it unfortunately so there's probably some other important details I've missed. Long story short though, it looks like we'll find out soon enough.[/spoiler]

Clarity control is a darkness artifact, (edit) Clovis found it after the k1 artifact from the moon (its in the black engram shaped structure in the crucible map anomaly) which sent him to europa, there after awhile of thinking of ways to helps reduce the exo body rejection (carn’t remember what its actually called) he found that passing radiolaria (edit 2, Clovis renamed/called it Alkahest) through clarity control more or less bleaches it clean of anything vex and he used that to upload human minds. So in a way exos are the human versions of the vex. Edit: i’d also like to add that its mentioned in the torn out entries of clovis’s journal that Elsie aquired an artifact of the traveller to stop clarity control. So we can now confirm the traveller has artfiacts maybe a little similar to the moon’s artfiacts that are in the anomaly and the one we gave to Eris. The question is if we go to clarity control will we be able to recover it?
