He nods, though it leaves him a bit uncertain. If his decision had no impact he'd probably go with whatever seemed easiest, and if it was critical then naturally he'd go wherever seemed like it needed somebody the most. The fact that it's not exactly either leaves him searching for another criteria.
Ultimately, after reviewing the worlds and objectives two more times, he settles on Dualentera. He feels familiar enough with how this sort of worldbuilding can shake out, the ways magic and gods can be shaped, to have some meaningful informational advantage here, and to think that situation is solvable with the introduction of someone who is aware of the big picture and does want to solve it.
Moving on to the available equipment (and non-equipment forms of empowerment, of which there are plenty), he spends a while browsing all the options and occasionally muttering combinations to himself, and a longer while selecting and then de-selecting them, considering each one more deeply.
Finally, he arrives at his final selection: Dualentera, with Custom Body for a basic tune-up of his extant physiology, Gift of Tongues, the Dualentera-standard allotment of Basic Equipment, Light of Creation, a basic local Identity just to make things a bit less cumbersome when he starts doing proper diplomacy, a Skill Upload for military tactics and strategy at the superhuman level, the Cognitive Package since it seems like he's going to need it to keep track of everything, the Perfect Diplomatic to make sure he doesn't make any really basic faux pas during diplomacy, and his major selection, Extracalibur, to raise his personal combat ability to a level relevant to a low-level orc and give him some guidance on how to stay heroic in the midst of everything, as well as to give him the means to attack and kill the various hard targets like Deathbringer, Alzena, the pair of troublesome gods.
Before he submits his selections, he turns to Agent Grey. "I don't know if I can ask whether this seems like a...uh, if there's any obvious mistakes, I guess, that I've made? Could I go over my gameplan here with you?"
