Biology[]
Behemoths were mega-bioships of the Extinction Fleet. They had the appearance of Garm Whelks. Vessels with great shells with seemingly endless spiral patterns and sporting cascading rows of thick spikes on their hulls, with massive soft tissue layers on the underside that spat out crystalized projectiles that liquefied on impact.
