Rayvians are decorative bird-like creatures found in The Overgrowth and several areas of The Moss Blanket. They were added to the game in Update 0.3.5, and went unnamed until their names were confirmed in a tweet by Monomi Park.
Appearance and Behavior
Ravians vaguely resemble beakless birds with white plumage on the tops of their bodies, while underneath they come in a variety of colors; purple, yellow, orange or light blue, and typically fly in a group in a circular pattern. When in The Overgrowth, they continuously fly around The Overgrowth's central platform. They spawn when The Overgrowth and several designated spawning locations in The Moss Blanket are loaded, and begin to fade after anywhere from ~5-15 seconds. The only way to respawn them is to unload and reload the area. Ravians cannot be interacted with and do not serve any apparent purpose, solely existing as non-interactive environmental decoration.
Their name, "Rayvian", is a portmanteau of "ray" and "avian", meaning "bird".
