Making their first appearance on Factpile and part of the Cthulhu Mythos, the Great Race of Yith are beings of immense intelligence and psychic powers.
They use their psychic powers to travel across time and switch bodies with lifeforms to learn about other races. Originally from the dying world of Yith, the Yithians traveled to prehistoric Earth and created a great civilization before being destroyed by the Flying Polyps and forced to travel even farther into the future.
In their grand cities, they have numerous libraries containing information on all creatures and races in the past, present, future, and beyond including the complete history of humanity from it’s infancy to it’s death.
In this battle, we pit only the Imperium against the Yith.
Will the Imperium of Man survive the might of the Great Race of Yith, or be destroyed like many others by the Yith?
