Banshee-44 seems to be expecting you. "So you're the one who blew up that old Servitor? Good riddance, that thing's better off as scrap."
"Got something for you. Ikora said you needed an Arc weapon." The weapon that he hands you looks untouched, fresh from the armory. "This can jolt, just like you. Should play well with your armor and abilities."
Banshee goes back to his work, but not without a parting word. "Bit of advice, Guardian. Get used to seeing Ikora if you want to keep learning."
Check back with Ikora to continue learning about your Light, including learning about other Aspects, Fragments, abilities, and keywords.
