Twilight Banner

(One use only)
Woven from spider silk and embroidered with the hair of nymphs and virgins, this banner can only be seen by night. Its protectors can blend into the ether for a few moments, passing through obstacles like ghostly shadows.
The twilight Banner can only be used in the Remaining Moves section of the turn (so a unit cannot use it on the turn it charges). They suffer no movement penalties for moving over difficult terrain or obstacles, or from any other reductions to movement. They can move through buildings just as easily. but cannot move through other units. In addition. they cannot end their move inside impassable terrain. These effects work only for that one Movement phase.
