Created by a group of ancient artificers, he was a nameless healing drone who healed with the holy light sealed within him and his thurible. The artificers were kept in prime health for almost two centuries until eventually the last one lay on their deathbed of old age, and with their dying words they gave the drone the greatest gift of all... a name... Azoth..

He wandered the world looking for purpose. All he knew was to heal, and for a time, he simply healed people he came across until he came across a group of adventurers and realised adventurers always need healing.

He was never built with combat in mind, but has a built-in magical shield to protect him from minor damage, and later attached a panel of lightweight metal to his arms to serve as a physical shield. He chooses not to wield a true weapon, instead striking those who get too close with his thurible. (It's a mace just reskinned as a thurible)
