I think I saw the artefact in her inventory after she joined, and transferred it to the PC, without her complaining. Well, it looks the same, and has an ominous description. There are a lot of inconsistencies like this in EA, though.
I noticed the same thing and thought, wait a minute, her whole character story that we know so far is about that artifact but then in game she just happily let the PC take it from her inventory like "sure, you carry it for a while".
