Ancient Serpentine city buried beneath the Sea of Sand following the Serpentine Wars, this site was also known as the Lost City of Ouroboros. It is the only known Serpentine city, and seems to be a mixture of different styles of architecture. In the center of the city is the infamous Slither Pit Arena. Legend had it that the Great Devourer slumbered beneath the city, and it is possible that the spirals and circles that appear so often in carvings in Ouroboros may refer to its presence. After Pythor successfully awoke the giant serpent, the creature badly damaged the city as it broke free. Despite the damage, it would still be used as a Serpentine base in later adventures and continues to exist today.
