===The Big Blue Hole===
<small>''created by starship''</small>

The Big Blue Hole is a sinkhole 1000 meters across. Soundings have estimated it's depths at 20000 meters. This is far deeper than a normal sinkhole and even deeper than the nearby ocean floor. The Big Blue Hole is widely regarded to have been artificially created after the sea was raised but by who, how, or why is a mystery. The Hole produces a tremendous warm upwelling of nutrient laden water that results in a massive amount of sea life. Many species are unique to this location only. As if that wasn't enough to attract divers there is a massive amount of shinies present in what seem to be tombs. Unlike Earless burial sites found elsewhere that were buried horizontally along the ground these seem to have been buried vertically along the walls of the hole. Retrieving these shinies is made more difficult by various species of aquatic life that are very aggressive. It is unknown what lies at the very bottom of the hole or how the upwelling is being produced. A specialized submarine would be needed to reach those depths.
