Endren (5e Race Variant)
From D&D Wiki
The endren half-elves are so called for their founder, Endryn Wallestyr. He was a high elf who led some half elves to break away from mainstream society and pursue the truths of nature, as per their fey heritage. This eventually developed a sort of philosophy and way of life that resulted in changes within the members of the endren. They are believed to be incredibly attuned to their natural energies such that they do not even need to eat or drink anymore. They often refer to themselves as "fey-descendant" while other elven varieties call them endren.
