DS9: Fearful Symmetry
and TNG: Q & A
have cameos by alternate iterations of the mirror universe where the Terran Empire survived into 2377 and 2380, respectively. Given what MU: The Sorrows of Empire
established about interstellar militaries and politics in the late 23rd century, I wonder how the aforementioned cameo realities could have come about. I conjecture that it would make for an interesting media project like the Abramsverse, but with the sheer amount of cruelty and killing that the Terran Empire entails, how could it live up to Gene Roddenberry's legacy?
