Outworlder

The Outworlders are a mysterious race of beings that have allegedly come from the sky. In "Letter to the Sky" by the scholar Archilo Duvan, he mentions the Outworlders "visited on repeated nights, before contstructing a mighty tower, where they lived and seemed to scout the nearby area before disappearing." While another claim says the Outworlders "emerged from the 'Under-Earth' and abducted cattle and children before returning to their homes." Most accounts claim the Outworlders came from the heavens, building what's simply known as "The Outworlder Tower" which is a a tower that stands tall over the surrounding areas, built with a strange unfamiliar metallic material and emitting a bright glow at night.

Appearance
In "Letter to the Sky", the Outworlders are described as having their faces covered in an odd metallic material, and wearing clothing that covered their entire bodies. Parts of their clothing "flared" at night. While the 'Under-Earth' claim gives them a similar appearance, although without any mention of flares, it describes their true appearance, apparently with "large piercing eyes and a slight permanent smile, as if to mock you."
