Just found this fusion rifle relic farming draksis that is asking me to talk to banshee-44. I haven't seen anything about this so I was wondering. Also I'm pretty sure the RAS stands for Rasputin.
EDIT: sorry guys got ahead of myself and thought I'd found something amazing.

I've brought in four myself, I feel we need to find a certain amount (7? it is Bungie's favourite number after all)
