Aepthi

The Aepthi are a bipedal plant-based race of creatures that come from a planet called Fuzzdl on a plane of existence in the Bubbly Vertex.

The Aepthi are humanoid in shape with a head that resembles a petaled flower. They appear to have visited our plane in the distant past and are the origin of the ancient runes scattered about the country. They communicate by vibrating different "petals" on their head in sequence. Research also appears to show that our atmosphere is toxic to them and their plane's atmosphere is toxic to creatures of our plane.

When the Aepthi speak, different petals on their head move to create distinct sounds. Their written language is originally based on a circular diagram with a space for each petal. The sequence of a single word is captured by tracing the order of petals moved.
