The Heroes of Feather Falls
No beings rule the chaotic and changeable plane known as the First World, but its most powerful residents are the mighty beings known as the Eldest. Sometimes known as the fey-lords, they each pursue their own mysterious goals, and have little interest in the doings of lesser creatures. All command great respect or fear from the other inhabitants of that strange realm.
The Eldest are extremely adept at molding the substance of the First World to their will, so their domains are oases of stability on that constantly changing plane—albeit oases that move around with their masters.
The Eldest were responsible for creating the fearsome living weapons known as the Tane, and could unleash them once more should they feel the need to do so.
Presumably there are many Eldest spread across the infinite plane, but Faerun has only felt the influence of the nine whose realms are or were coterminous with this particular part of the Material Plane.
