Slea

Slea - (slee - ah)

Slea is a dragonoid demon born in the human realm and lives with her mother, who is not so kind to the humans that inhabit the realm.

Slea and a human boy grow up together, their friendship being forbidden by both her mother and the Slayers that sought to remove her from the realm. After her mother's demise, Alton and Slea flee the land together, in hopes to escape the Slayer's that hunted her down. 

After eventually destroying the slayers, with the help of Alton, Slea takes over a human woman's body... whose broken soul ends up being thrown into the clutches of a fire lord, and is later then created into the angel of demon parts- Nala.

Slea and Alton are oblivious of what they'd done to that woman's soul, and the future events of which they've stirred into motion, by Slea inhabiting her empty human shell, and the two live happily together from then forward. 

They have a child by the name of Symphia.

Unfortunately, Slea later dies from a 'strange disease' as Alton tells the villagers and his daughter. Forced to keep the true reason quiet from everyone but himself- and of course, logging his finding into the magic book he'd been writing for years. This 'disease' is not actually a disease at all, as it is Slea's soul is being torn in two, after giving birth to Symphia- she unknowingly passed her soul power over to her daughter, and as her daughter grew older- finalizing at age 13, lead Slea to slowly break apart on the inside- tearing her soul out of existence.

This 'disease' is later passed on to Cutts, when Alton transforms himself into a demon via magic. He takes the original 20 foot dragonoid form of his beloved wife, Slea, without realizing it.

The disease is altered slightly, and refuses to be the end of Cutts, it causes terrible problems for him in the future, but does not lead to his demise, as it makes him wishes it will.
