Hmmmm, I interpreted this as an adjacent space to the creature being attacked. Thematically I figure if the target gets hit they would be moved away.
Man, this game needs an FAQ badly...
Looking through the cards I actually think it is a square adjacent to the attacked creature becuase there is a flying creature with the same ability. Since a flying creature is not actually on the board, how would it move the attacked creature to a square adjacent to itself?
But yes, a FAQ would be awesome. I'm sure there is one somewhere...in Russian...
