- For the TLJ chapter, see The Chaos Storm.
Chaos Storms are huge, terrible storms that appear in Arcadia from time to time, usually lasting a single night. One of these storms appears while April is en route to Alais and is responsible for the sinking of the White Dragon. According to Tun Luiec, Chaos Storms are storms caught in a magical vortex, and are harbingers of terrible events in the near future. She also says that Chaos Storms are weapons used by dark forces to destroy those who are strong in the Balance. April therefore believes the appearance of the Storm near the ship is connected to her. Given the frequent attacks from the Chaos Vortex, the Storm may be related to that.
