The latest expansion to Destiny 2, Forsaken, is kicked off by the tragic death of one of its main characters. Cayde-6 is brutally killed, and much of the campaign revolves around tracking down and exacting retribution on the faction that destroyed your beloved Hunter mascot. Now that he's passed, you can pay your respects by visiting an Easter egg dropped in his honor.

Spotted by user Atomic-Yeti on the Destiny Reddit, Cayde's cloak is now hanging up in Holliday's hanger inside the Tower. It sits on the wall right behind Holliday herself, near her computer equipment.
