The Taken Path

The Taken Path is the Exotic quest for Barrow-Dyad in Episode: Heresy Act I. The player finds a hidden Taken Blight during a Nether run (one of three locations), collects the Taken Osseous Fragment, then interacts with the slab at Eris Morn's apartment in the Last City. The quest runs a couple of hours and ends with the Derealize Exotic mission, which drops Barrow-Dyad with guaranteed Deepsight.
