Much later in the 41st Millennium, [[Cypher]] revealed that Tuchulcha was embedded within [[The Rock]] and that the [[Dark Angels]]' dark history of [[The Fallen]] could potentially be changed by finding the other two engines and changing history. He also warned that Astelan and [[Typhus]] both sought the engines as well, the former trying to ensure his rebellion would be a success (talk about a pipe dream) and the latter attempting to join forces with his past self. Eventually all 3 devices were gathered, and a warp rift was summoned over the ruins of Caliban. 

''''''It is done, the plague-lord will no longer interfere. We will be remade.''''''

Convinced by [[Ezekiel]] to leave history be and to focus on trying to prevent nearby Fallen and Death Guard forces from accessing the rift first, [[Azrael]] destroyed the rift leaving the status of the other two constructs unknown, and it also had the unforeseen consequence of {{Blam|+++absolutely nothing of note happening.  Any further questions should be forwarded to Interrogator-Chaplain Zacharias and [[Ordo Chronos|his strange new friends]].+++}}

Later still, it was stolen by [[Vashtorr]], who recognized it as the last piece of the "Key" he and [[Abaddon]] sought to create. Reunited with the Plagueheart and the Ouroboros, the newly reforged Dissonance Engine was used to link Wyrmwood (formerly Caliban) to numerous Webway tunnels, allowing the Warmaster and his daemonic ally to begin their search for the Lock, a cache of superweapons predating the War in Heaven able to annihilate the galaxy.
