The general idea is that it seems really, really odd that all the way through Heavensward Urianger knew about you, but suddenly decided to go through Moenbryda's belongings to find a dues ex machina that, theoretically, could have helped you much sooner. Right before you go up against Lahabrea, nonetheless.

If that's not completely suspicious, I don't know what is.

That or it's just SE being lazy in their storytelling method and not finding another way to give us a white auracite so they're like "Let's have a long-dead character just have a spare item of incredible power and usefulness, because no one really checked."
