Magic. How well will it work on the planet? Namely; Healing magic, Apparition, Telekinesis, things of that nature.

Admittedly apparition I've partially nerfed myself in that he'll only be capable of heading to places he's already been, but well.. for sake of plot well, one could distract the man from thinking about abandoning everyone just to give people heads up on what's happened. Especially given that Sinthia's signed up to be possible victim I doubt the man would abandon any children, regardless.
