The law is the ultimate expression of civilization, my son. That is what John's father told him repeatedly, and it is what he believes. Joining with the church of abador he quickly proved himself as a reliable, effective bringer of law. Assigned to the wilds near Barrjka he fought savage orc and ruthless bandit. He solved crimes and upheld the law.He technically worshiped a god, but he really worshiped the law, and the symbol of that was his pistol. He made it himself. It was hard hitting and reliable. Then one day while cleaning it, The law betrayed him.
All he saw was a bright flash and then he woke up in a hospice. Blind. His magic healed his hand, but eyes, they were harder.
He was informed that the church had decided that it was his incompetence caused the accident. The law decreed he was to blame for that and for the deaths of those he was to protect. He was dismissed from the laws, and the church's service, although technically he was still a priest. Not that it was willing to support him. Abandoned in this hospital he was an object lesson to what happens to those who opposed the rich and powerful.
Sitting in his room john cleans his pistol, waiting for something. A sign that purpose still exists. That justice still exists. With opportunity, justice will crash down on those who defy it. But blind, what can he do.
And then an offer arrives. A miracle, a sign. His sight returned, to be exchanged for services. Tempting. Very tempting. John thought hard about this offer. The law had failed. Justice would replace it, and then a new law, a better law will be enacted. His pistol was not the law, it was justice.
He would take the offer, and and take up justice. The guilty would fall.
A miracle, a sign. But good or bad. John intended to find out.
