Amos

Amos is a servant of an unknown royal of the West, who specializes in experimenting on the maledicted and benedicted.

Appearance
Amos is a handsome man with tawny skin with short, light-blue hair. His yellow eyes with slit pupils are usually covered by round sunglasses. Additionally, he sports several piercings on his left ear.

Background
Amos is the leader of the organization "Onyx", which focuses on experimenting on people who possess magic, be it people affected by a Malediction or Benediction. Thanks to his unique power, the organization doesn't struggle to collect victims and to report whatever findings they have to their superior.

Malediction
Amos was cursed by Ferna, the Celestial of Hope. Because of his Malediction, his eyes are not human-like. Instead, their sclera is colored yellow, with slit pupils similar to a cat, which is why he is usually found wearing sunglasses. With the power bestowed by the Celestial, he can inflict pain and temporarily manipulate another of their powers by looking at them, causing them to experience a different effect than intended, resulting in a feeling of hopelessness and rendering them useless. For that to work, Amos needs to maintain a stead eye contact, as the effect ends upon interruption.

Amos' glasses are an artifact that help him control his powers. His Malediction is designed to slowly blind him over time, then slowly spread through his body. Once the effect is spread out, he will suffer from the same kind of pain he was able to inflict on others, only it would not end, torturing him until he dies.
