The Xapiri Thëpë or "Spirit People" in the language of Yanomanni Indians are an elf metavariant native to the Amazonian Basin. They have chlorophyl patches on their skin and have an allergy to toxins. There are believed to be under 10,000 such individuals, all of whom seem to live in tribes.

Researchers at the University of São Paulo believe that the chlorophyl was introduced by magic, although this seems contrary to current theory.
