The Nentir Vale is Doomed
Vistani are a nomadic people who travel in caravans of rolling house wagons, storage wagons, people, pets, and livestock. Well known is the fact that such Vistani clans roam the world, the Feywild, and the Shadowfell. Less known is that each clan has elders that know rituals and sites to cross between these planes. Hence, a Vistani caravan might be found anywhere in the parallel worlds between the elemental and immortal realms.
Without homeland, the Vistani roam the world and its reflections. They weave enigmatic stories of their past, and their ways are inscrutable to outsiders. Vistani clans, full of folk of differing races, rove outside the politics and concerns of civilized places. Their magic and guile allow them to safely traverse the dark gulfs between settled areas and cross the walls between worlds. To sedentary people, these numinous vagabonds bring exotic goods, news, services, and skills. They take away new friends, orphaned children, and survival essentials, as well as more valuables than, perhaps, they honestly earned.
Vistani is not a race but a supernatural blood connection between folk of various races who
have grown up in or joined Vistani clans. Only through the Vistani Blooding Ritual can you become a Vistani. The Vistani share an uncanny similarity in eye color, which is glossy black. Every Vistani also has the violet scar from his or her Blooding, which other Vistani can intuitively identify. (This mark turns black on Vistani outlaws.)
