Astarael Fontaine/Astarael Lightbringer

Astarael Lightbringer is the son of Remillia Fontaine. He is mentioned by his mother many times over the course of the story, although so far he has not made any appearances. Astarael is mentioned to be currently on a trip to Pyandonea.

Events mentioned
Astarael was born to Remillia when she was about 40, as evidenced from her speech. While he was given away for adoption by Remillia, Astarael sought her out when he was only five and they had a close relationship, although not that of a normal mother and son, rather more like an aunt / nephew relationship.

Astarael and his mother began to grow apart when he found out how she financed her lifestyle. After Astarael got married, his wife detested Remillia. As such, Astarael and his mother's relationship soured considerably.

Remillia still hopes to see him again, though. She has never given up the hope that they might reconcile, even though she knows the chance is slim.

Appearance and personality.
Astarael's personality is unknown. Remillia mentions him as a "nice boy" and seems to see him as relatively filial. He is evidenced to be caring towards his own family, which he places before his mother. Astarael probably has the same attitude as his uncle Raphael when it comes to fights, using practical movesets to kill his opponents as fast as possible.

Appearance wise, it can be safely assumed Astarael looks like his uncle Raphael, except younger.

Powers and abilities
Astarael's powers and abilities have never been discussed by Remillia, except for the fact that his energy projection is so great, he would make Raphael look like a nobody. His name suggests that his energy projection is in the form of light, although nothing said by Remillia confirms this.

Astarael's skills with the blade can also be assumed to be equal or superior to his uncle's, since he is known to his mother as a spellsword.

Trivia

 * Astarael is practically the man Raphael's family wanted Raphael to be.
 * Astarael is not slated to appear in the Roleplay. He is simply mentioned by his mother. This makes him seem like a whispered legend, rather than an actual flesh and blood character.
 * Astarael's powers are deliberately left hazy and unknown.
