When you crest the ridge, you rein in your horse and stop to look back at the trap you have set. After several minutes, you see your enemy enter the valley and gallop along the trail. You magnify your vision in order to observe them as they approach the pillars, but as they pass by the obstruction, you detect no sudden release of power.
The enemy have failed to trigger your trap and now you have lost a precious advantage. Cursing your ill luck, you urge your stallion to the gallop and speed away from the ridge with your ranger companions following closely on your horse’s heels.
