The Waterborn Peloran are based on the standard Peloran genetic codex with heavy modifications to operate underwater. Their lungs include the ability to filter out unhealthy levels of nitrogen and other gases, and to keep them from bubbling out in potentially damaging ways. This makes them mostly immune to most pressure ailments and decompression issues. Their skin is designed to blend into and better survive the underwater environment, and their eyes can detect wavelengths only seen far beneath the surface. They do still need to breathe air though, which limits their dive durations to what the air supplies in their armor can support. Despite this limitation, they were deemed fully functional as warriors and the Albion kept their genetic codex in full production until the very end.
