Beastman

The beastmen (マンビースト Manbeast) are a race of hybrid animal-humans that mutated over the thirty years since the Golden Sun event at the end of The Lost Age. Following the explosive event above Mt. Aleph, various humans began to grow fur and fangs, while various wild animals began to grow in size, stand on two legs, become sapient and gained the ability to talk. Many live in Morgal, a country in the northeast of Angara. Morgal's capital city, Belinsk is effectively populated entirely by beastmen. Some are said to have special powers, although the only beastman whose abilities are seen in detail is Sveta.

History
Some time after becoming beastmen, many were oppressed by Sana. This changed when Volechek rebelled against Sana, and, in a violent uprising in which the previous Sanan Emperor was killed, successfully established his own country, Morgal, with Belinsk as its capital. Though no specific reason brought them together, over time, many beastmen gathered in Belinsk, making it a haven of sorts for the beastmen across Angara.

Ancient Beastmen
Even though the emergence is a relatively recent phenomenon, beastmen are known to have existed during the time prior to the sealing of Alchemy. They are known to have worked alongside the Jenei as indicated by the Umbra Gear being designed specifically for beastmen but little else is known about them.

Trivia
