-1739 CE-

A group of Cavale traders embarked from Kuzeycol at high noon on a fine day for sailing in their ship, loaded with trade goods en route to Ankalvanian ports. As they sailed north, a fresh breeze started to blow from the southeast, and puffy clouds began to form in the sky. Before long, sailing conditions rapidly worsened all around the Northern Cavale traders' boat. Soon, towering thunderclouds poured rain and began to rumble, as gales began to propel the lone boat off course, and waves continually crashed against its hull. As night fell, the sky began to be colored by continual flashes of lightning as waves pounded against the ship's deck, and the sailors realized they could no longer right their course.

All through the night, the sailors of that lone boat were caught up in what grew to be a tremendous tropical storm. On numerous occasions in the next few days, it seemed as if their lone boat had endured its last, but the ship remarkably stayed afloat until the storm finally forcibly grounded it on an unknown island. There, the sailors discovered numerous mysteriously abandoned stone structures, all half buried by nature. Among these ruins were what appeared to be various temples and numerous houses, along with two granaries and two graveyards, separated by the overgrown remains of walls twice the sailors' height or more. Even the grandeur of two abandoned palaces could be seen atop the island's highest area, both separated by the aforementioned walls. The sailors could only vaguely pick out two words within their cavernous interiors, without understanding their meaning: 'Gregorii' and 'Gregoria'.

To this day, both the cause of the great city's downfall and the Cavale traders' fate remain unknown.
