Etymology and taxonomic history[]

The first confirmed report of a Taishë came from a book on the fauna of the Tai region of the Lios Federation. The book had been published in 32. Experts believe that the mentioned Taishë was a lone specimen.

A pod of Taishë off the coast of Haven Bastion in 324. James Galtson, a naturalist on the merchant ship Seravį, spotted them at dusk in early Latcharion. He managed to sketch a pair of adults and gave them the scientific name Aicarisa mirus, meaning winged whale in Selean.


There is little, if any, sexual dimorphism between adult Taishë. Both males and females grow to an average of 5.2 meters and weigh around 145 kilograms. They are covered in feathers, but there is a thin layer of fur under the feathers. They move by flying, using magic to maintain flight. While they look like sea whales, Taishë have hind limbs that are used in flight.


Females tend to reproduce around 5 years of age. They remain pregnant for 4 months and tend to give birth to twins. They raise both twins for 10 months, at which point the young can care for themselves.

Males become sexually mature around 6 years of age. Taishë pairs are monogamous for life, and males help females raise their young.


Taishë live in pods that have up to 45 members.
