The Collector exited the Snowmound with its mana fully recharged its force of thirty-three evolved champions, one evolved elite, and elder in tow. A female champion carried the elder on her back, bundling him up in a series of insulating fur layers to ensure the cold environment did not compromise his health.
There were certain limitations imposed upon the Collector's mobility in harnessing this swarm of units. Mostly, these were limitations based upon the evolved specimens' physical needs. They required regular sustenance as well as period of rest within which to sleep and recharge their stamina.
Of course, now that the goblin variants were all evolved, they possessed far greater degrees of stamina and physical ability that would allow them to engage in treks that lasted throughout an entire day, but any longer than this, and their abilities could compromise.
