Andrew had taken a group of junior Slayers on a field exercise and they'd stumbled onto the opening of a portal.
A fight had ensued and the demons were vanquished, but an overenthusiastic kick had broken the ceremonial talisman. Andrew had grabbed the nearest object and intoned a spell to reseat its power.
