Senna
Senna ’s journey to become a Sentinel of Light started with darkness. It started with the Black Mist… Senna first encountered the Mist at an early age, when wreckage from a distant Harrowing washed onto the shores of her home island. The Black Mist within the wreckage awakened upon contact with life. She and her village survived the ensuing storm of souls, thanks to the intervention of a nearby Sentinel… but in the wake of the attack, the Mist was still mysteriously drawn to Senna.
