Shaxx is kneeling in the Courtyard, petting a happy warbeast pup when you approach.
The Crucible handler looks up at you. "Guardian—have you ever rounded a corner in the Crucible, and suddenly been face-to-face with another Lightbearer?" he asks.
"Yes, they have. Oh yes, they have!" he coos to the slobbering puppy. "I watched it happen!"
"In situations like those," he tells you, "a hand cannon is the final word in short-range stopping power." He gestures to the firearm holstered at your side.
"I commissioned the first Luna's Howl as a gift to someone who lost their dearest companion on the Moon," he says, lowering his voice in tribute.
"I'm reviving this model so that you'll have a reliable companion of your own against the Witness," he concludes.
"And speaking of companions, pop in on Zavala, will you? With all this stress, I fear he's looking… a little blue."
