Hyathis is the "Panala" (Queen) of Alstair in the Antares solar system, Alstair shares the solar system with four other planets: Dhor, Llarr, and Mosteel which is farthest from Antares. Hyathis appears to be a "Plant Elemental" with empathic control over all plant life on Alstair. Alstairans are all plant/humanoid hybrids because they diverged from the common protozoan evolutionary branch linking Flora and Fauna much later on than life did on Earth. All plant based Alstairans receive part of their nourishment from sunlight and have broad leaves instead of hair. The mold based Alstairans appear to pass on the mold infection with a vampiric bite, they also prefer darkness and seem to have stringy hair.
