Dispelling Darkness

From: Vera
Description: Kira is right: what if the anti-fog crystal still works after the cleansing? We could bet on it and build a device that will bring the crystal’s beam up to the surface. But this would require your tools, please lend me some.
Completed: I’ve treated the symbiotic mineral with nitrogen. I’m now making an incision and injecting the saline solution under the mineral’s surface... It’s working: the parasite has escaped, releasing the anti-fog crystal, whose bright beam reflects in my device and now bursts up to the surface!
