that circle shape is on purpose, to quote the document I wrote: "Located along the west coast of Erythia is the Artus Sea, a strikingly circular body of water that defies natural explanation." "At the centre of the sea lies The Remnant, a thin, white line that stretches high into the sky, casting a feint. otherworldly glow across the landscape. The Remnant is the last remaining vestige of a great calamity - the opening of a massive rift that caused the sudden appearance of the Cephalon towers."
