Many ages ago the Kirsi were free spirits, traveling between different arcane sites throughout the year. An ancient woodland stretched across northern Anhault, and in the wood on the Dusa River, there was a site of great power -- High Hill. Many creatures were drawn to High Hill: the sea monster Aachen made his sometimes home in a flooded cavern nearby, and souls from the restful plane Hereward opened a portal nearby. So, the Kirsi decided to make their home there, communing with the sea monster Aachen and the Hereward souls. The Kirsi clan Raven House was the priestly house, and Raven House set up the Kirsi god Boreas -- who takes the form of a stone idol -- on High Hill. Over time the god Boreas drew great power from the hill.

The Kirsi continued to live near the hill as free spirits, except for Raven House. Now settled in one place, Raven House became fascinated with building and crafting. Soon this extended to the martial arts, and they become fell warriors. They built an arcane forge for weaponsmithing across the river from High Hill, near Aachen's flooded cavern. Of course, all of these things -- High Hill, Aachen's cavern, the Hereward Portal, the Raven Forge -- are where Hollin is now.

After an age there, a human clan arrived in the wood and discovered the Hereward portal. Of course they wanted to go to the restful plane, so they became determined to drive the Kirsi out and claim the portal, but Raven House stood against the human warriors on High Hill. The humans fought cruelly, but they were just mortals, and Raven House routed them. But on the verge of breaking, the humans called on their god Gradska, and Gradska sent his angel of death Kidu against the Ravens. That day Kidu's coming was heralded by a white burst that outshone the sun and seared my vision; a ringing sound spread across the whole wood like a shock wave and lingered in my ears. When the ringing subsided, Kidu appeared in mid air surrounded by a nimbus and floated to the ground. He surveyed the scene, and it seemed to me that he took to wiping out Raven House with sadness. But he did wipe them out, or nearly so. Just a few Raven survivors came back to the main Kirsi camp near the Raven forge.

There seemed to be nothing the Kirsi could do to stop Kidu from crossing the river and wiping out the entire camp. The camp was breaking up and scattering in horror when a figure appeared on the edge of the camp. He looked human, and at first the Kirsi assumed he was from the human clan. But, he had our god Boreas wrapped in a cloth, and he marshaled the Kirsi, moving them out west along the shore. He protected the Kirsi rearguard from a human attack until they could find the cover of the larger wood.

Over the next few months the figure -- who we called Huldremose and you call Prosper -- led the Kirsi west, through many dangers in the wood. We reached Shear Pass, and Prosper held off the necaratu swarm there while we hurried one-by-one over the Murnen portal bridge and the vacuum of space below it. We came into the valley here and settled. Over time we extended our fairy domain to include the abandoned human cities we call Balibana and Gaillard.

Prosper stayed with the Kirsi until we were established safely in Renhannes, then took up the life of a wanderer, but always keeping an eye on our valley. However, at one point we noticed that he had stopped returning, and we started to ask each other what had happened to him. Since then, we've looked for him everywhere our fairy eyes and ears can go, and only recently have we started to see fresh instances of his rune -- one on the Tolland Stone and several in Hollin.
