Homebrew Coatlaca Species Details

The Coatlaca appear mostly human at first glance, with smooth skin, sharp features, and an eerie, graceful presence. Their most striking trait is their serpentine mouth, which reveals long curved fangs when they speak or smile. Their eyes are often slitted like a snake’s, and many possess unnaturally pale or vividly colored irises reminiscent of jade, gold, or storm clouds. Their movements are fluid and deliberate, giving them an almost unsettling elegance.

Many Coatlaca have subtle serpentlike traits—slightly forked tongues, elongated canines, and an uncanny stillness when observing others. Their hair is commonly dark and straight, though some display faint feather ornaments or ritual markings honoring their storm-serpent god. Despite their human appearance, their calm gaze and predatory smile make it clear they are something older, colder, and touched by divine serpentine power.
