Fiction
TransTech
During the "Mass Reemergence", numerous Mini-Cons in the Aurex Cluster suddenly appeared on the Transcendent Technomorphs' scanners. These Mini-Cons, with their great power, subsequently became pawns in the Autobot-Decepticon war, eventually attracting the attention of Unicron, who sought to use them to make himself more powerful. In what could only be described as a Primus miracle, the Mini-Cons combined their power to single-handedly defeat Unicron. Afterwards, an uneasy peace emerged as the Autobots and Decepticons did not want to provoke a similar response; the Mini-Cons demanded to be left alone. The TransTech named Heinrad then emerged into this Aurex universe and offered the Mini-Cons a choice: stay and help the Autobot-Decepticon war effort, or leave to live in peace in Axiom Nexus. Most chose the latter option. Rook - Axiom Nexus News, 2015/05/09

Luckily, that was just the Shroud and not the whole batch of universes dying.
No, that happened on New Year's 2016 when the TransTechs penetrated the Shroud to find all of Aurex was gone.31/12/2016, Rook - Axiom Nexus News
