Searching for Mystical Dust

From: Kira Woodville
Description: I was six when my parents arrived here in the City, before the Distortion. They were gold-diggers, but they left their mine for the sake of mystical dust, which was mined from the City's Rift. We worked day and night to see at least a couple of glowing particles in our mineral trays. Somewhere here was a sample, let's find it.
Completed: That's not gold in the tray you found. It's soil! Upon contact with particles from the Rift, it acquired new properties. I'm sure that this attracted the Collector to the City.
