In ages past, the elder races spread out over Etharis and carved out separate kingdoms for themselves. Then the first humans came and all but annihilated the other races in their relentless drive to multiply and expand.
Today, humans are still the most numerous and powerful race in Etharis. The elder races survive either in isolated remnants of their own domains, or incorporated into larger human kingdoms. But it is an age of crisis, and some see the opportunity to claw back what their ancestors lost.
Though they are reduced in number, members of the elder races are a common sight anywhere in Etharis. Perhaps because they so often live on the fringes of human civilization, they also make up a disproportionate number of its adventurers.
Some playable race options that are available in other worlds are not options for this setting! Because of the sheer level of superstition and distrust present in the world of Etharis, monstrous races are not present in any adventuring party and are, as such, not included in Playable Races. Additionally, the Feywild is a major unknown to this world and traversal through it and/or knowledge of it would fall under the same superstition that the populace has of monstrous races and would not be present in adventuring parties.
