And Here, There, or Yonder does not say explicitly that an ally does not need be playable at given (target) site. "if the result is greater than 6 plus the ally's mind stat and the ally is not restricted from moving in this site's region" does not preclude this usual requirement of playing ally."
I think though there are no examples in the game of an ally who is restricted from moving at a site he/she/it is playable at? Therefore it follows that the card must allow the playing of an ally at a site where he/she/it is not normally playable? So while as you say it doesnt explicity state the ally does not need to be playable, it is inferred by a process of deduction. For example, if I say to you "I am not a woman" you would infer that I am a man?
