Pelagon
this ocean-covered planet was the first world settled in Tapani Sector, more than 13,000 years before the Battle of Yavin. It was settled by the ships of the Pella Compact, which maintained government of the original colonies for a thousand years. Over the millennia, cities were built over the warm seas, and great continents were formed from manmade structures. Over time, the wastes of these cities began polluting the oceans, and by the advent of the New Order, the seas of Pelagon were unable to support life. As House Mecetti rose to power, power struggles led to the destruction of many of these cities, further littering the oceans with debris. There were rumors that the ruins of many floating cities were protected by the spirits of the ancient Jedi Knights. Note that the Players Guide to Tapani also refers to this planet as Pelagia.
