[MW Voidsea] Chuulverin - CR 8 Huge Aberration

“Not many people can say they’ve survived being shot from a chuulverin’s cannon. I’ll admit, I don’t remember much after I crashed headfirst through the enemy’s hull, but the concussion was almost worth the bragging rights.” 

—Sharkas Blackcreek, Retired Cannonball

The sight of even a single chuulverin’s cannon rising up from the water’s surface is a terrible omen, for it tells all present that the abolethian armies have committed everything to the oncoming assault. These rare and mighty specimens are deployed only sparingly by their masters—generally when a battle must be bloody, swift, and utterly crushing.

Ancient Artillery. When the aboleths sought to usurp the gods, the chitin-plated chuulverin stood among their most valuable weapons. Acting in the capacity of military commanders as much as living siege weapons, these crustacean colossi rasped orders to the lobsteresque legions from the rear while unleashing volleys of sulphurous artillery upon the battlefield. Under a chuulverin’s command, all crumbled before the relentless advance of the chitinous swarm—iron hulls, fortress walls, and eventually, the resolve of any who opposed them.

Smoky Gestation. Though aboleths seed seas and caverns across the world with nests of chuul eggs, only those buried near volcanic vents on the ocean floor give rise to the dreaded chuulverin. There, protected by crushing pressure and shrouded in the boiling darkness, the eggs steep in plumes of mineral-rich smoke. A chuulverin requires a full year of gestation before it finally crawls forth from its deep-sea crucible, wreathed in a metal-infused shell and endowed with living artillery fit to sink fleets for its aboleth masters. 

Organic Ordnance. The bony protrusion on a chuulverin’s back resembles a cannon in both form and function—only instead of powder and shot, it contains a portal to the depths in which the creature was born. Through this portal, the chuulverin draws superheated water under tremendous pressure, launching it in powerful jets that shatter wooden hulls and pulverise stone walls. Occasionally, a mature chuul egg is dragged through the intake and violently hatched on impact.
