"Aye, it’s a strange world, alright. We’ve got elveses, and dwarveses, and the halflins and the gnomeses, and all them kind of peoples. And we’ve got old Oograglah, that goliath who comes ‘round every couple o’ weeks. And there’s that troupe of orcs who come in for the winter – they’re a queer bunch, but they sell their furs at the markets, and we keep our eyes on them. And I went up to Endon’s Pass last summer, and you wouldn’t believe the folk I saw: there was cat-people and lizard-people and dragon-people, and one young lady with wings as big as an ‘orse!"
-- Rigbold of Whitehill, consummate traveller.
In modern days, Endon is a metropolitan mix of races from all across the world: humans, elves, dwarves, gnomes and halflings are the most familar, living in and around the cities, towns and villages scattered across the kingdom. Though humans are the most common inhabitants, many would not be surprised to meet the rarer races in the taverns on Endon’s highways – tieflings, aasimar, goliaths, and even some of the bestial races. Some races are unpopular, met with suspicion if not outright violence in places, such as the orcs, the goblins, the kobolds, or the yuan-ti. But, for the most part, all are welcome.
Being so old and established a kingdom, however, Endon has developed its own particular sub-races over its history, as the protected valley has cradled and allowed them to flourish. The goliaths that live in the Iron Mountains have a rich history and a vibrant culture, though they seem standoffish and quiet to those that they meet. The yuan-ti of Endon, though, who survived the genocide a thousand years ago, hide in the shadows and wait for the day they may return to the surface world: their endurance and secrecy has imparted them with particular skills that allow their continued survival.
There are, of course, more races than this that live within the Valley of Endon, but these three are the particular specialisations that have cropped up within the girdle of the mountains. They are responsible for and live within some of the most iconic Endonian landmarks – the Feywilds, the Ssthessic ruins, and the Agdu.
Other races that have lived within or around Endon for milennia, such as the dwarves of the Iron Mountains, the orcish tribes that wander the steppes to the west, and the humans subjugated as slaves for centuries do not differ overmuch from the others of their race.
