This unfathomably large serpent sports a distinctly draconic face. Its body is deep, blackened gray with swatches of crimson. An entrancing set of lures dangles off its face, each glowing with a pulsating orange light accented by regular electrical discharges.

Breath Weapon (Su)
Once every 1d4 rounds as a standard action, a sea linnorm can expel a 120-foot line of intense stored bioelectricity, dealing 26d8 points of electricity damage to all creatures struck (Reflex DC 34 half). A secondary discharge arcs off each target that fails its save, striking the nearest creature within 30 feet as long as that creature has not already been targeted by the breath weapon or another discharge. Secondary discharges do not cause tertiary discharges. The bioelectricity overwhelms the nervous systems of living creatures, causing any living creature that takes damage from the linnorm’s breath weapon to be stunned for 1d4 rounds. A successful DC 34 Fortitude saving throw negates the stunning effect. Creatures struck by a secondary discharge receive a +4 bonus on this saving throw. The save DC is Constitution-based.
Death Curse (Su)
Curse of Crushing Depths: save Will DC 32; effect creature takes 3d6 points of damage every round while fully submerged in water, as though suffering water pressure damage, regardless of the creature’s actual depth and bypassing any magical protection against water pressure (such as freedom of movement or life bubble). The save DC is Charisma-based.
As a free action, a sea linnorm can light the dangling lures on its head; any other creature within a 120-foot radius that can see the lure must succeed at a DC 32 Will save or become fascinated for 1 round. In addition to the regular effects of being fascinated, a creature affected by this ability also takes a –4 penalty on saving throws against the sea linnorm’s breath weapon. Regardless of the preceding interactions between the sea linnorm and its target, a creature affected by this ability does not view the sea linnorm who has fascinated it as a potential threat until that sea linnorm actually attacks—allowing it to approach without breaking the fascination effect. Once a creature succeeds at its saving throw against this effect, it is immune to the same sea linnorm’s lure ability for 24 hours. The save DC is Charisma-based.
Environment cold oceans
Few, if any, linnorm breeds are more reclusive than the sea linnorm. These immense specimens of primeval draconic lineage dwell in the deepest underwater trenches of the world, blending into their surroundings thanks to their darkened scales. A sea linnorm’s distinctive facial lures attract all manner of sea life, which the linnorm promptly feasts upon before returning to its lair. Luckily for all nonaquatic civilizations, sea linnorms rarely leave the ocean depths they call home.
A typical sea linnorm grows up to 55 feet long and weighs around 14,000 pounds. It is believed that sea linnorms are effectively immortal, with the oldest recorded sea linnorms surviving well over 5,000 years.
Electricity courses through a sea linnorm’s body. The linnorm uses this internally generated power to fuel both its facial lures and, when necessary, its devastating breath weapon. This natural attack manifests as a powerful line of orange bioelectricity that overwhelms the nervous system of any living creature in its path.
The innate bioelectrical energy of creatures struck by the breath weapon further empower the attack, creating additional discharges that arc off the breath weapon’s naturally straight trajectory toward the nearest living creature. When the linnorm uses this attack to hunt larger underwater creatures, the subsequent discharges quickly overwhelm entire schools of fish for the sea linnorm to devour.
Luckily for the surface world, sea linnorms rarely have any reason to depart their deep underwater homes.
Teeming schools of aquatic megafauna roam in the depths that sea linnorms inhabit. This primordial wildlife is of such size that a waking sea linnorm rarely concerns itself with having to roam far for a fulfilling meal. After eating, a sea linnorm hibernates for years, or even centuries, at a time. In some instances, entire aquatic settlements spring to life near the hidden lair of a sea linnorm, only to incur the beast’s excessive wrath when it awakens from its slumber. Some of these unfortunately placed settlements even adjust their entire societies to provide for “their” linnorms, shepherding schools of fish toward the beasts’ lairs and, in harder times, encouraging visitors to visit the linnorms’ dens.
Habitat and Society
Sea linnorms inhabit the deepest trenches of the world’s oceans. Only the abundance of large underwater life sustains the voracious appetites of the bioelectrically charged beasts. As a result, a sea linnorm’s perceived territory encompasses a space of several thousand square miles. Any sentient creature that the sea linnorm perceives as a threat is sought out and slain. Those few settlements permitted to exist within a sea linnorm’s domain are used as early warning systems; each settlement is seeded with traditions of alerting the great linnorm to the presence of potentially threatening outsiders or of certain types of aquatic alpha-predator life-forms, such as krakens, luscas, or sea serpents. A sea linnorm immediately seeks out intruders, recognizing that it will either triumph or die—better to be slain fighting in the open water than cornered in its lair.
Few mortals know of the existence of sea linnorms, let alone hunt these ancient creatures.
