Personality
Mathias has never really cared much about humans. They've always been nothing more than a food source. When it comes to interacting with others, Mathias likes to stay in the background and under the radar. A little bit paranoid. Sometimes it is within good reason. Things have proven to be unpredictable with others of the same species.
Bio
Mathias was preying on a human when an old rival appeared. This caused conflict and resulted in both being injured. Mathias was very weak. The other demon couldn't be any better though. This led Mathias to retreat to the nearest shadowy place available where they might be any easy food source to heal from. Mathias was too weak to attack anything, which led to the willing feeding of a human... From this, a bond was created that would never be broken and Mathias' entire purpose for existing changed.
