Pilvi are gaseous, sentient cloud people. when they travel beyond their world, they generally need to wear a suit that encloses them so their particles don’t evaporate or blow away.
When they are on Parvi, the Pilvi people practically float, their form is almost like a snowman, they look like someone walking on the moon, but their bodies are constantly swirling. They don’t have defined limbs, but they can control their form to manifest appendages for use as needed.
When they go off-world, they often wear special space suits that contain their being, so they don’t get blown away.
