Luka

Luka is... disturbing... 

theyre probably insane at this point

but Piia has an interest in them

Skelle is a bit iffy on trying to interact with them :V

Luka scares the absolute shit out of Citrus and Gemini

they also have some disease (called "Bleed through disease") that lets their blood be visible, but that doesnt stop them from going on land
