The County of Reivelin was one of the realms of the Outregam, during the Middle Human Age, being a vassal of the Kingdom of Avaynti. It was a human, high and grey elven colony set in Polforia after the First War of the Power, as part of the colonization efforts to civilize the former demonic lands.
Aside of the settlement of north western Human and Grey elfs, along with some Ushaerian High elves, in Reivelin were to be conquered and resettled demon-worshipper humans such as the Kdaimons and Blood elfs, who were seen as corrupted by the demons but salvageable: The Demon Servers were resettled in mixed settlements with the colonists, but often in a subsidiary role as servants and serfs of the settlers, as it was seen that as the settlers were saving their souls from the demons, they had to repay with service:
