- “ And the day I found the DarkLight Emerald, it gave me exactly what I needed: the power to rule the Never Sea! ”
- ―Lord Fathom
It is currently unknown when or how Lord Fathom acquired the DarkLight Emerald,but during his time harnessing its great power Fathom was able to control the mighty Strake in his first attempt to defeat King Neptune, and would have defeated him if it wasn't for the combined efforts of Neptune and Captain Colossus sealing both the Strake and Lord Fathom. But in the process, Captain Colossus lost his battleship to the depth of the Never Sea. To assure that the DarkLight Emerald wouldn't harm anyone King Neptune gave it to Queen Coralie who locked the emerald away in deep within Neptune City for years.
The Darklight Emerald is the source of Lord Fathom, which, when placed in his trident, gives him the power to control the various creatures of Never Sea. It also has the power to fire bolts of green energy and manipulate the sea itself to his whim and bring back sunken shipwrecks under his control. However, without the emerald Fathom is virtually powerless.
