Thunder's Edge: Echoes of Memory

A Twilight Imperium Novel

By Sarah Cawkwell

After a strange meeting leads to dire prophecies of a horrible future, a Hacan war hero must chart an expedition across the galaxy to locate a mysterious planet to save the universe from destruction in this high stakes thrilling space opera tie-in to Twilight Imperium: Thunder’s Edge.

Harrugh Gefhara – the Golden General and retired leader of the Hacan – wanders the deserts of his homeworlds seeking answers and escape from the galactic intrigues of his past. When a traumatic meeting leads to a dire warning about the destruction of the universe, the reluctant hero dons his armor once more and gathers old friends and foes to explore the mysterious planet called Thunder’s Edge. Guided by a peculiar artifact and visions he cannot understand, his expedition into uncharted space quickly becomes one of pure survival as he and his crew suffer a sneak attack from the insidious Nekro Virus, crash landing them in unknown territory. There, they discover the foretold ominous plans for the future are worse than Harrugh ever imagined and it will take all his cunning to outwit the fate the Nekro has in store for the galaxy.

Twilight Imperium

Intergalactic empires fall, but one faction will rise from the ashes to conquer the galaxy.

Once the mighty Lazax Empire ruled all the known galaxy from its capital planet of Mecatol Rex, before treachery and war erased the Lazax from history, plunging a thousand star systems into conflict and uncertainty.

Now the Great Races who span the galaxy look upon their former capital hungrily – the power and secrets of the Lazax await a new emperor…

To lay claim to the throne is a destiny sought by many, yet the shadows of the past serve as a grim warning to those who would follow in their footsteps.
