The Tower is a mysterious, gigantic superstructure of unknown origin. It is presumed to predate human civilization, based on cave drawing which depict it.[1] It is reffered to as "Aminara Tower".[2]
Location
The Tower's precise location is currently unknown. Each character claims to be in its close vicinity[3]. It's uncertain whether they all see the same structure, or if there are multiple towers. Mars' explanation suggests it's in South America,[4] Sari lives near a structure which resembles 3 smaller towers,[5] Claw is shown to live in the Tower's shadow[6] and Ryann lives in it.[3]
