Chronicles of Ascension
Pallones are disclike creatures, ranging from 2 to 5 feet (0.6 to 1.5 m) across, and as thin as the thinnest blade. They reﬂect light, have no discernible features, and are semitransparent, similar to how a jellyﬁsh looks in the water. When seen from the side, they are nearly invisible.
Pallones move through the Ninth World in a migratory pattern and can be found almost anywhere (assuming they can be seen at all). Typically, PCs can detect them by catching a glimpse of their surfaces gleaming in the sun. When in a natural state, the creatures bob along in the air aimlessly, much like balloons.
