The Nature of Nomad Infiltration

[Windstar]

I'm inclined to agree that infiltrators, to be effective, need to retain at least most of their host's mind and personality. I rather like the notion that they're still in there, albeit corrupted and changed as Niemann or Tekagi seemed to be. They have changes to their activities because of shifting priorities and goals ofc, but they still had little quirks and such that one could reasonably infer as belonging to the host's former self. Their psyches, in that sense, could live on as "edited programs" in a way. Masks to be worn.

Infiltrator uses both nomad and human parts to control and indoctrinate humans. That is why humans must stay physically near the Infiltrator to become Thralls. Spacebound Nomads can't replicate this since they aren't this compound organism. Incubus can't do it on its own without a host, either.

This does incidentally result in a vast undercutting of a lot of Nomad player RP. If Nomads cannot psychically affect humans in their spacebound forms, it renders a lot of avenues of expression and interaction noncanon.
