How stealth really work ?

[Chazar]

I am resurrecting an old thread, yes, but are there any independent/summonable/mercenary spies around?

I guess this might be hard to tell, since there is no icon for it, but am I correctly assuming that a unit is a spy if and only if it may instill uprisings?

Is it true that there is no glamoured spy? Why then is glamour a good thing? (I've found Illusionists - which currently seem pretty useless for me being Caelum...)

I think there are only two stealthy mercenary Groups, those wolfboys (although I might mix them up with Dom 1 ), and the master assassin.

I think there is an indy recruitable unit called spy, but that's about it.

Also, there's an assassin you can get from a random event, Im not sure if he is a spy though, I havent checked =P
