A Fenrisian Wolf Pack may only be chosen as a Retinue for a model with both the Legiones Astartes (Space Wolves) and Master of the Legion special rules. This Model is referred to as the Fenrisian Wolf Pack’s Leader for the purposes of this special rule. The Fenrisian Wolf Pack does not use up a Force Organisation slot and is considered part of the same unit as the model taken as its Leader. The Fenrisian Wolf Pack must be deployed with the model selected as its Leader deployed as part of the unit and the Leader may not voluntarily leave the Fenrisian Wolf Pack during play. A Fenrisian Wolf Pack may not be selected as part of an army without a Leader.
