I really want to like this card, but I feel like its use is really limited. The most it will do is negate the the of two locations (having one copy as the active location, and having the other two in the staging area). the chances of this happening, though, especially in low player counts, are really limited. Most of the time, you will only be negating the of one location in the staging area, and even then, this is not guaranteed every round.
In a quest like Danger in Dominion, or any quest focused on locations, this could have some uses. I suppose it prevents location block--but is it really the effort to cross? My opinion: not really, in low player counts. There are definitely better side quests with lasting effects. Still, it's good for Thurindir, and the artwork IS amazing.
