Soldat's goals are basically extermination of mimic spirits (or negotiation and removal which he will try first, but he doubts they'll listen this time when they didn't last time), and finding the body-wearing spirit to negotiate either a return to the surface or a truce/protective relationship with Weaver, and hopefully a release of the (now severely decomposed) bodies. Otherwise, he's just backup for everybody else.

He fully supports Cao Pi's second priority. Let us yeet World Eaters into a dead dimension or something pls. If he gets the chance, he'd also like to collect any information on World Eater language and behavior, if there is any.

He comes fully armed with two handguns, lots of knives, a variety of snacks to maybe bribe mimic spirits with and also eat himself, moderately fluent command of the spirit language, and origami paper.
