Bracken wanted Trey to install some tiny jets in her leg to help out in battle, but Trey was worried about putting her in danger. Instead, he designed a new outfit for her that made her just as excited, except he now has to build it. The first item he wants you to find is two sunset prisms. You can get some from either Mining Camp No. 2 or Mining Camp No. 5. Bring them back to Trey and he’ll ask for two somnium nuggets next. You can acquire these, too, from Mining Camps, but only 4 or 5. Return to Trey with these and the quest will be finished.
