A prosecutor is a headmate whose role is to protect other members of the system from external harm, traumatic memories, harmful members of the system, or other threats. Unlike protectors, prosecutors will be willing to take drastic measures to protect the system, and will punish those who wrong the system. They can be quite vengeful, but do not ever intend to harm the system itself.
