These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Awesome: Supreme Warmaster Gar'shan calls his final battle a masterpiece for a good reason: with an outnumbered, outgunned and demoralized force composed mostly of rookies and second rate forces, he managed to inflict obscenely disproportionated losses against the Allied fleet... Including the long-range bombardament ships of the Hyach Navy, forcing the survivors to fight into the range of the Dilgar fixed defenses' guns. All of this before throwing the remaining elite of the Dilgar into battle.
Faux Symbolism: one example of which the author is not even responsible. The Dilgar launched their genocidal rampage to escape their sun going nova. Earthforce dreadnoughts and latest model of starfury are named Nova-class , and Earthforce heavy cruiser class (the same class of the EAS Persephone, the first Earth warship the Dilgar fought, when it obliterated five times her mass in Dilgar warship before Jha'dur arrived with her fleet. Then the Persephone charged Jha'dur's flagship) is named after Hyperion, the Titan of the Sun. Had Lord of Misrule named them instead of the authors of the tabletop game, it would have highly symbolic of Earth's role in the war.
Also, according to J. Michael Straczynski, Earth's most advanced weapon technology are nuclear fusion bombs, that makes use of the same reaction that fuels stars, and Earthforce is quite nuke-happy, perfecting the Faux Symbolism.
Nightmare Fuel: According to legends, if your ship is destroyed when it's in the vortex to cross in hyperspace you'll never die, being locked in the moment of death forever. In-universe, that's actual source of nightmares for many spacers, and Sha'dur the one who could have said if it was actually possible, actually died when his ship was rammed in an hyperspace vortex by a Markab cruiser.
What happens to the Dilgar victims. If you're particularly unlucky, you may piss off Jha'dur, and that's even worse.
The timing of the Drafa Plague. Did it remain dormant for centuries or Jha'dur recreated it to exterminate the Markab?
