From D&D Wiki

A Trident used to defeat the legendary behemoth Leviathan. Crafters can create Leviathan's Bane with 3 units of Dark-steel and Orichalcum each. The great sea god Poseidon gave this to a great Triton warrior in his greatest faith, now lost to history, with the task of controlling the great titan Levithan. But with a titan fighting a servant of a god, they fought, and descended into the darkest abyss in the plane of water. neither gaining a significant advantage. Eventually they were lost to history, and the weapon too. But it is whispered that when the creature rises once more, a new Heir chosen by Posiedon shall rise up to it and defeat the Titan and bring peace to all denizens of all seas, lakes, and oceans alike. If one that finds it and claims it and may not be the Heir, may be mistaken for it and either revered or hunted.
