The Covenant of Primus delves into the depths of Transformers mythology to reveal the backstory that's previously only been hinted at. Encased in an interlocking Autobot emblem that when pulled open emits Transformer sounds, this tome is a gift to humans from Alpha Trion, one of the ancient Thirteen Primes - the first of the Transformers. Little is known about Alpha Trion, and the rest of the Thirteen Primes have been shrouded in mystery - until now. The Covenant of Primus reveals the stories of these ancient heroes for the first time. Never-before-seen illustrations depict battles, portraits of the Thirteen Primes, and detailed scenes of the Transformers' world.
