Your Thorn hums with the hungry indifference of the Void, but it lacks something essential. You know the original Thorn was intimately connected to the Hive, though you don't know exactly how. Wandering around the Tower to ask your mentors about the provenance of a banned weapon strikes you as a bad idea, but— There are quieter places to ask questions. Places off the beaten path, where knowledgeable Cryptarchs have settled down to do their work in peace and quiet… Pay a visit to Tyra Karn at the Farm. The Farm is accessible via the EDZ Director.
