Nights in the Tower are often quiet, provided there isn't a major event going on. Tonight is one such quiet night, and you are fairly surprised to see Cayde-6 awake when you walk into the Hangar-- you'd been prepared to just leave a note about your completed bounties. Cayde's reading over some reports, but looks up when he hears you walk in.

"Hey there, Guardian. Been a long day?" His voice is full of sympathy, and he motions for you to come over.
