Prior to the War of the Threefold Spark, the tabernacle of Tarn-Hauser Gate held a compendium of wisdom from the ancient Cybertronians. When Alpha Trion regarded it, Ultra Magnus noted that, in a time of war, the tabernacle, and other cultural artifacts, would be the first to fall to the conquering army, leading to a discussion about cultures in warfare. Years later, Ultra Magnus would come to appreciate that Trion had been attempting to educate him on sympathy for the enemy. Storm Horizon Part 2

Trivia

• "Tarn-Hauser Gate" is most assuredly a Transformerized reference to the "Tannhäuser Gate", mentioned in Roy Batty's famous death monologue from the film Blade Runner. Showrunner F.J. DeSanto also confirmed in an interview with Rodimus Primal it was also a nod to Hasbro Studios exec Mike Hauser.
