Protheon Shard

Protheon Shard can be placed into the Microscope to get Protheon. You get one Protheon Shard from Welchie, a Novakid questgiver in the lab of Vinalisj (on the starting Garden planet). It has an extremely small chance of appearing as loot in the wild.

After you identify it in the microscope, you can also throw it into the Hand Mill or better extractor.

Warning: don't throw it into the computers! It would be a waste of valuable artifact.
