Leneor's supporter - Äeon

Aeros knew his supporter from the very first time he met her, the time she wasn't a supporter. The truth is, that she is his bigger sister, who loved her brother tenderly, allways watching for him and being by his side. During the start of the great war, she was one of the victims being cought and brought into one of the witch towers, which were the base of experiments. During the time there, she herself found out about being a witch, but managed to hide it from everybody, in order to stay with her brother and give him solace, and to protect him.
that was unbeknown to the other witches, and even so she was tested and experimented on, it wasn't discovered until the fated day. It was a gruesome experiment, which had injured her heavily. during her last minutes of life she chanted a spell on herself and the very vow she had made to her brother the day they had entered the tower;

"I'll allways be there and protect you, Leneor, don't worry and don't cry. I will keep all evil sealed away, as long as eternity, if that is what is needed to see you smile again."

The witches had seen the truth far to late, as her talent and supply of mana would rival amongst those of the four great witches. The mana that was poured inside her vow was an event that became sealed amongst the witches of the tower, despite the fact that anyone in great distance had felt something rushing through them during Aeon's spell.
Seeing her potential far to late, the witches used the blood of his very sister to inscripe a complicated patern of old runes in the boy. After this they made cruel experiments with him, like trying to ressurect his sister by sacrificing his soul, but despite all those experiments, of which only one had driven a normal human insane or killed him, the boy kept smiling, as all bad he experienced was sealed away within a gate, guarded by his very sister.

Aeon is the exact image of his sister during the time of his ordeal, and shares the same personality, as if it was her soul, bound to Leneor. Her yellow eye seems to penetrate everything, and see things which should not be seen - emotions,memories and character within a human. Her bandage and the horn stand for the ordeal his sister had gone through to guard him.
the horns being the symbol of a Queens disposition amongst witches, broken due to her death.
The bandagages being the symbol of sacrificing something important, to safe something greater.
