These strange figures act as the hand of the Sarion king himself. With special permissions and resources at their disposal, Nightstalkers carry out the will of their master at any cost. So fierce is their loyalty that many believe they are compelled by some dark secret to serve the Legion agenda. Who knows? Perhaps time will tell.
The Nightstalker is a master of disruption, causing opposing characters to miss turns and reducing incoming damage to his allies. A little tip: use him only at night.
