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
