On the night before her final battle with Bel Shalor, Tira Miron gathered her companions together to discuss and outline her vision for the Church of the Silver Flame. Most of her words were preserved in records kept in Flamekeep, but not all of them.
Tira took one of her adventuring companions aside, the elven paladin Samyr Kes. Samyr wanted to fight at Tira's side when she faced the archfiend, but she ordered him to stay back. She told him she could bind the fiend, but she couldn't destroy it, and the binding wouldn't last forever. There would be those who heard his whispers, and those who would do his bidding. She wept as she detailed what she needed Samyr to do, because she knew it would destroy him to do it, but no one else could do the job. Samyr's mission was to watch for these people, save them if he could, but if it came down to it he was to put the safety of innocents ahead of those corrupted by the Shadow in the Flame.
Tira's companions did as she asked after she sacrificed herself to bind the overlord, and founded the Church of the Silver Flame. Only a few know of the orders she gave to Samyr Kes, but she had made clear to everyone that they were to cooperate with what he asked, and to give his new order everything it required. Samyr named this new order Miron's Tears, after the tears she wept as she assigned the task.
Today, the order is a ghost within the church. It operates with utmost secrecy, and not even Jaela Daran is aware of it's existence. It draws recruits from those within the church who have shown themselves to be resilient against corruption and fiendish influence, and demonstrated exceptional devotion to the church and it's mission. For hundreds of years, the order of Miron's Tears have fought a secret war against fiendish influence in the church, wiping out cults of the Dragon Below and exposing fiends. Due to the secretive nation of the order, it's members serve and die without their accomplishments ever being known or attributed to them.
