A fiend is a personification of evil, a native of the Lower Planes. They are the dark equivalents of celestials.
Fiends include Tanar'ri, Baatezu, yugoloths, gehreleths, Night Hags, barghests, rakshasas, baatorians, kytons, baernaloths, hordlings, Avari, and Diakka.
Denounce passion. Uplift death. Feel the embrace of the True Death..and sink into Oblivion.
