Howling Griffons Bladeguard Veterans Illustration that I did for the new Space Marines Codex.
The Tervigon is a massive creature, with a towering spined carapace that shields a swollen abdomen. This massive Tyranid organism serves as a living incubator capable of spawning Termagants. Beneath a Tervigon’s lumpen carapace dozens upon dozens of Termagants slumber in a state of hibernation. The Tervigon spawns its dormant broods at will, so that a foe engaging it will soon find itself assailed by waves of skittering Termagants.
