Transformers: IDW Collection Phase Two Volume 5

At the dawn of the conflict, battle lines are drawn and sides are set... now legends will be made in PRIMACY. On current Cybertron, Shockwave sets into motion a long-gestating plan but Soundwave, now commander of the Decepticons, confronts him in the ancient Crystal City. On the Lost Light, Rodimus leads his crew to the gates of heaven-or something much worse as larger forces close in and an ancient plan is reaching fruition.

Collects Transformers: Primacy, Transformers: Robots in Disguise #19-22, and Transformers: More Than Meets the Eye #17-22.
