Aphelios

Aphelios is mute. He strives to serve and protect the Lunari. He has a sister in the spirit realm who speaks to him through his mind.

Emerging from moonlight’s shadow with weapons drawn, Aphelios kills the enemies of his faith in brooding silence—speaking only through the certainty of his aim, and the firing of each gun. Though fueled by a poison that renders him mute, he is guided by his sister Alune in her distant temple sanctuary from where she pushes an arsenal of moonstone weapons into his hands. For as long as the moon shines overhead, Aphelios will never be alone.

With his sister being gone more often, Aphelios grew desperate for purpose. He decided to perform a ceremony which would reveal one's path. In doing so, he discovered a pool where poisonous noctum flowers grew. The blooms could be distilled into a liquid that would open him to the night's power - however, drinking it caused Aphelios to feel so much pain that he became numb to everything else.

One day, the Lunari temple, the Marus Omegnum, began to come into phase to emerge from the Spirit Realm for the first time in centuries. Every time the temple opened, a person gifted in magic was chosen to occupy it. Alune was chosen to be the occupant. Lunari from around the mountain to watch, and Aphelios, who was not known for asking for things, asked to attend.

But as the halls of the temple entered the physical realm, the Solari discovered the ceremony. They attacked the Lunari, defeating Aphelios and causing him to reach for the noctum flowers and eat one. Alune rushed deeper into the temple and eventually reached its heart. There, her magical abilities were amplified. Through the poison in Aphelios' blood Alune could give him power and give him new moonstone weapons.

Alune drew herself and the temple back into the spirit realm to keep it safe from the Solari. Inside, she could send power anywhere, as long as it had a focus, like the poison in Aphelios' blood from eating the noctum flower. With this newfound power, the two of them vowed to protect the Lunari at all costs.

the twins are both devoted and mysterious individuals but also extremely caring and protective of each other
