The Dead King's Scepter grants its possessor the ability to generate earthquakes strong enough to sink islands and continents, such as it did with Atlantis long ago.
It also allows its possessor to control the Trench through primal authority recognition. The sceptre was destroyed when Arthur forced both it and him into an open lava vent during the final battle for the kingdom itself.
The scepter had a replica fashioned after it, one bearing the same power as the original which was buried within the false tomb where the Seven Treasures were first found. It was kept within a hidden chamber no one knew of, while the forgery was laid with its creator at the real resting site of the Dead King.
