Arctic Zerg Lurkers under command of Ashrah the Axe Of Breath are the organic ultimate in winter stealth.

Ashrah was always religious person, who seemed to be worshipping Protoss as at least a demi-gods. Terrans, who sooner or later joined the Axe Of Breath were even more willing to become infested by Arctic Zergs, fighting for their faiths.
