Continuing the Atlantic Corps refs with their Sea Divison! From left to right we have:

• Midodo, resident space case who may or may not be part sea critter but she gets the job done so nobody complains.
• Aoo and Aii, a pair of twins who are the new kids on the block and whose genders are a mystery. Aoo is the foolish twin and Aii is the responsible twin. Very ostensibly.
• Murara, the resident old fogey whose been hardened by the years they spent out at sea.
