Viola is a Blue-aligned merfolk from my MTG fan-plane of Stellatium. They are both an engineer and a pilot for a faction known as the Technoceanus Shipwrights, which are a center Blue faction that builds, repairs, and invents ships, probes, mechs, hedrons, and satellites. Merfolk on this plane have lower halves that resemble octopi and these extra limbs prove useful for managing the controlling of ships or slipping them into tight spaces to repair for many merfolk. They can also change the color of their skin and most tend to rely on sign language or changing the color of their bodies to communicate(something that is very helpful when you are underwater or in the vacuum of space). Viola had their lower half replaced with a mechanical prosthetic due to them being born with the octopus-like arms of their lower body almost completely missing.
