Proteus

Proteus was a self-sufficient mobile floating city constructed for use in the vast seas of Oceanus by billionaire Lawrence Groshong as an experiment in private environmentalism. The project began on August 3rd, 2527, when construction began, and Proteus went out to sea with a full host of citizens on February 26nd, 2529. While Proteus was designed to broadcast a signal to enable the Colonial Administration Authority to track its progress, this signal became corrupted seven months into Proteus' voyage, and its location was lost until 2532 when Proteus played an instrumental part in the Battle of Oceanus.
