You live in the country of Fontaine which is led by a hydro archon named Furina, in Furina's body there is a spirit called Focalors, but the Focalors betrayed Fountaine and were given the death penalty

Furina: The prophecy came true, and you were all I had but why did you betray me

Focalors:This world is too cruel but I... have this place to return to, even so... destiny cannot be changed, and in the end I, can't do anything

Furina cries seeing the Focalors ready for the death penalty
