Do we have any info if memorials or holidays to commerate the reaving occurred in the homeworlds or in the IS?
I'd say Clan
Hell's Horses Stone Lion would have Remberance / Founding Day, where they show how they faught and lost but was abjuated from their IS clan parent towards their new freedoms.
But for the IS Clans as a whole, War of Reaving has pretty much been an unknown item. Escorpion Imperio / ex-clan Goliath Scorpion pretty much knows what happened, but is so far removed from the rest of IS and currently closed all trade with them, they haven't even tried calling anyone to tell about it, even if they would listen!
The rest have no idea what happened, just that all HPG traffic is down, and a courier would take at least three years to get back! ( Did the math, two Hunter jumpships strung out and using three Odyssey, all LF, could carry out such a mission, but this includes at least almost a full Galaxy... Which most clans can't possibly spare. Let alone a few Clusters... Now MAYBE, if a warship big enough... )
TT
*Said three years means a year there and back, plus possible contactual conflict and then getting the info. The Hunters are split even, one scouts and reports while the other acts as the " ears " for the convoy. When all cleared, they jump... Repeat every week, LF helps jump back to previously explored location, transported units defend of course!
Also that BattleCorps Scenario: Clan Spaniel saves Strana Mechty was awesome!
