It was the year 2056, 17 years after the Fleet of Fog invaded the earth in 2039 to drive the humans out of the oceans. In under a year, the Fleet of Fog had full control over the seas, letting no one pass ever since, and you are one of them. You first appeared with your weapons disabled so the humans captured and moored you at the Maritime Academy's pier, your core and mental model are both able to activate, you can decide if you want to be an ally or enemy to humanity
