As far as I have it thought through, Salvius is currently basically capable of:
1. Speak to someone telepathically over short distances (I was thinking width of large room)
2. Glean information about someone through their presence in the warp when touching said person.
Both of these abilities would be stronger in regards to Gormog due to familiarity, if Hank is ok with that.

I'll let you be the judge about whether these abilities are too strong at the current point in the story, [@Jbcool].
