Peregrine Knights are described by the couplet "the peregrine, whose bell always rings the crack of breaking day, it's nameless peal will drive the ceaseless evil from the ways." Implying that they wear bells as the mark of their order and protect roads from evil.
Peregrine knights are tasked with the maintenance of shrines and the King's Road. They spend their entire lives walking and staying in pilgrim's shrines, none of which they stay at for long out of custom. They also work closely with the angels to maintain order and the monastery-fortresses that certain angels hold.
Certain angels are tasked with the repair and keeping of their monasteries (wherever they are), though most of the busy work is done by orders of the knights Peregrine, who work closely with the angels to enforce the peace and keep the King's Road clear of danger.
To leave the void and enter the physical world, Angels require bodies of forged ash. The Peregrine Knights are responsible for collecting the ash in the void. It is hard to collect and very hard to forge. Though due to internal strife over how to interpret the change of leadership in Throne, they have not actually forged anything new for about three centuries. As angels inhabit the same armor each reincarnation, the armor itself is cared for by the Peregrine Knights when inactive, or stored at Koss' Workshop.
Creating angel armor is very old, very powerful stuff - and very little is actually known about it anymore, even by the angels themselves. No new suits have been created in a long time, partly due to animosity between angels and the guilds.
There are countless small rivulets in the armor so the angel can control it. Angels fit into their armors like a key, and they can not normally be worn by something human-shaped.
- "Take care when ye walk when there's a dim age about. Many awful lights will spring up a-hungering when men's hearts darken. When the darkling sky reigns, a man's eyes grow so adimmed he can scarcely tell the glimmer o' window light asides from the terrible heat o' the forest fire." - Peregrine Knight Enric
