It is unclear if the Black Thorns were nuked, orbitally bombarded or died of the Galedon Plague. Their battlefield use is the same either way.
Hey, it matters! Salvage, man,
salvage. Plagues leave 'Mechs intact.
So, y'know, in several decades RL-time, a few centuries in-game, we can have Neo-Blakists fighting the Draconis Dominion and the Niops Commonwealth with ancient machines carefully refurbished on planets that "dropped off the map" during the WoB Jihad, right before the Fifth Succession War and the Invasion of the Clan in the 3300s.
Man, that is
weird to think about. Someday, TRO:3085 is gonna be the equivalent of TRO:3050 today. We'll have things like TRO:3085U, and some new format of record sheet, so the MUL we all have downloaded into our brains won't have things like the
Flamberge or
Targe, and people will rail against Catalyst's successor's successor's successor's successor's successor about releasing the MUL "before it's done." And then Deathshadow's preserved consciousness, embittered by decades of forum hacks and silly complaints, will use the fully armed and operational MUL to incinerate the complainers' frontal lobes.
