Cosmic Storms are special types of storms within which To'kustars are born. They typically take place within Nebula.
To'kustars can allegedly create and manipulate these storms.
Cosmic Storms are violent clashes of energy akin to thunderstorms on Earth, but far larger and more destructive.
By nature, they can be dangerous to navigate a course through.
Cosmic Storms usually occur within Nebula, but can occur elsewhere in the cosmos. They can be created in the aftermath of a Supernova. Some are nearly as old as the universe.
