The Tale of Suma || The Lost One AU

Xisumavoid remembers nothing before they came. As a child, he and his twin were kidnapped for their magical properties to be used for unknown purposes. What lies beyond those walls of the tower he grew up in, he doesn't know and he tries not to care. His brother, on the other hand, dreams of nothing else than escaping. Are the brothers indeed fated to be compliant and used forever, or will one convince the other to escape once and for all?

Note: this is a one-shot that is part of a series, but can be read on it's own.
