Quintesson
From Multiversal Omnipedia
Quintesson was the homeworld of the Quintessons. As a result of Galvatron's time travel, a rift in time was created that destabilized the planet and its sun. The Quintessons began plans to colonize a new homeworld, but were thwarted in doing so; those Quintessons remaining on the planet were destroyed when their world finally died.
