Third Earth

Third Earth is the home planet of a wide variety of sentient and non-sentient beings of both native and alien origins. It became the home of the ThunderCats after Thundera was destroyed.

At one point in its past, Third Earth was known as First Earth.

Every one hundred years the planet has a total eclipse, any spell cast by Mumm-Ra at this time will last until the next eclipse.
