The Forgotten One

Background
The Forgotten One was discovered at the bottom of Verganon, a being surrounded by mystery, and its purpose unknown. It spouts things that will be, of a fate that Ryu cannot escape, and that he will eventually become the same as it. It speaks in a two toned voice, male and female, which to Yoli, sounds just like Ryu and Sacreia, until its transformation when a second woman's voice joins it.

During the battle, it speaks of a child that has been abandoned due to her actions, it is speaking of the original Leira, who created the 1000 year cycle involving Ryujin and Seraiya.

The creature wields copies of both Dresera and Xural and uses them with deadly proficiency. Upon its death, The Forgotten One releases the spirit of two spirits emerged from its corpse, of a former Ryu and Sacreia who were once the creature fused together. Only Yoli is capable of hearing their words, which alerted her to what Ryu will eventually become, and what fate awaits him. One that she hopes will never come to pass.

Appearance
The Forgotten One resembles a giant humanoid, with two skulls fused together at their sides. It wears an exoskeleton like a half dragon, and possesses a sunken face within its chest. It speaks in a two toned voice, male and female, that bear similarities to Ryu and Sacreia.
