Tales of immense sea serpents have colored the accounts of seagoing folk since the first ship sailed beyond sight of land. Yet proof of these immense and elusive creatures is remarkably difficult to come by, for not only is the ocean vast and the true sea serpent rare, but these creatures are quite adept at both avoiding capture and destroying ships bent on such a daunting task. Due to the sea serpent's hermitic nature, many sailors take to ascribing the sighting of such a beast to an omen, although whether the sighting portends peril or providence depends as much upon the ship's morale as it does anything else-the sea serpent itself has little interest in prophecy, and only its hunger determines how dangerous its proximity to a curious ship can be. Deadly danger surely awaits, however, when its spine-frilled neck arches up from the water like a snake ready to strike.

Descriptions of sea serpents vary with the region in which they are found. Sometimes they appear as giant sea snakes and other times as dragon-like serpentine creatures with legs or flippers. What is known for certain is a sea serpent can be encountered in any ocean, sea, or large body of fresh water. Sea serpents have two attacks. It has a poisonous bite for 1d6 points of damage and death in 1d4 rounds, save vs poison to negate; and a coiling attack which can crush a ship or creature in 1d6+4 (5-10) rounds. Sea serpents are very territorial but are not otherwise aggressive, only attacking when hungry. Once a sea serpent attacks, however, it is fearless and relentless and will fight to the death. Sea serpents are capable of diving to great depths and staying underwater for long periods of time. Sea serpents only lair in caves in very deep water and tend to be solitary or, at most, a mated pair.
