If the Enemy’s chosen action fails, then that Hero and its army will move.
The Hero and all Units in its Region will move in the direction based on the compass on the Action Card (orient the compass to match the one in the top-left corner of the Game Board).
The Hero's army moves 1 in the designated direction, if it can. If it cannot, it will circle clockwise until it finds a Region that it can move into.
When using the arrow, reference the center of the region and draw the line from there. If in doubt, go clockwise.
