Cloud Whales are the largest Atmospheric Beast. Surprisingly for a creature of such massive size, it is the most elusive; very little is known about them at all. Cloud Whales do not really resemble whales much at all: they are billowing thunderheads with three pairs of chunky flippers that wave out of sync on the underside. With large heads that taper downward into stubby tails and high-rising, upper backs, the shape is reminiscent of Humpback or Sperm Whales. Large specimens are almost only found preceding or alongside massive storms, hidden among other large thunderheads.
