The Kingdom of the Trench is one of the seven kingdoms that splintered off when the ancient Atlantis sank. The Trench that resides there has regressed into savage deep-sea beings. The "Trench" is often understood to mean "Mariana Trench" in the Pacific Ocean, but it is strongly implied to be found in the Mediterranean Sea, somewhere near Sicily, Italy.

In the depths of the Kingdom of the Trench exists a bright and violent maelstrom which is a one-way portal to the Hidden Sea at Earth's core. Only the true heir with the Trident of Atlan can bring people back.

After the War for Atlantis, the kingdom was among the kingdoms that reunited with Atlantis.


Becoming a solo kingdom

During a test with the Trident of Atlan, Atlantis sunk into the ocean. The kingdoms separated, and the Kingdom of the Trench evolved with its inhabitants becoming savage beasts. Deep within the kingdom, there is a portal to the Hidden Sea in Earth's core where the Trident of Atlan resides, only to be wielded by a worthy king.[1]

Atlanna's sentence

When Orvax found out that Atlanna had another son that was half Atlantean and human, he sentenced her to the Trench. However, she made it to the Hidden Sea and survived, and was later saved by Aquaman and Mera.[1]

Reunion with Atlantis

After Aquaman wielded the Trident of Atlan, the Trench were ordered to stop Atlantis from killing the Brine and their king and from attacking the surface world during the War for Atlantis. After the war ended, the Kingdom of the Trench was among the kingdoms that reunited with Atlantis.[1]
