IMMI'S ILLYANA RASPUTINA has been disengaged from this whole Wild West theme thing, waiting it out for the reset. She has a low opinion of humanity and of people who use others, so she's kinda on the side of the Hosts in spirit. Not going to help them, though!
ANAKIN SKYWALKER doesn't have his Force powers or his lightsaber as a Host, but he's still an almost unstoppable killing machine with his bare hands. (He even rolled a mere Chosen one for injuries.) If he gets those hands on a period-appropriate sword or two, it'll go faster.
