Looks to me like some kind of new beastman. Mostly because of the humaniod appearance. I expect we will know more soon.

The capital of Mamool Ja, Mamook was built deep in a forest on a peninsula west of the Aht Urhgan Empire.
In order to control parasite infestations, the wooden structures that cover the capital are burned down and rebuilt every few years. Therefore, much of the construction in Mamook appears rather crude. Like the Mamool Ja's equipment, the few intricate decorative metals in the area were created by prisoners taken by Mamook. Furthermore, sacred stones situated in each area of the capital are believed to harbor the spirits of fallen Mamool Ja heroes and protect Mamook from evil.
This highly treacherous area is legendary for stranding many a ship. It is for that reason that Arrapago Reef became the final bastion for a kingdom that was destroyed by an attack from Aht Urhgan. It is said that the kingdom's immense treasures still rest in the coastal caverns. However, the Lamiae are currently using the reef as their stronghold, guarded by the sleepless undead. Infiltrating Arrapago Reef would be no easy task.
The Mamool Ja are a group of beastmen that hold dominion over the Mamool Ja Savagelands, a land hostile to the Near Eastern Aht Urhgan Empires
Referring to themselves as the Mamool Ja, meaning "brethren of the shining scale," the inhabitants of the Savagelands are orgainzed into four biologically different classes that consist of warriors, aquatics, sages, and knights. The Mamool Ja have been paying tribute to the Aht Urhgan Empire since ages past, and are known for their republican form of government. Their nation is ruled by a council of four overlords, one selected from each class. The Savagelands' recent uprising against the empire seems connected to the emergence of a prominent leader known as the "The Autarch."
