You're right it isn't canon...
But I like it
Bravo!
I like it enough that if I ran 2300AD, it would be worth including as a footnote that
a) Russians have a phrase they use on their children that if they don't behave at night, the shrieking Asgarda will come for them.
b) Fellow soldiers from other nations joke about eunuchs in arms, literal 'ballbuster' girlfriends, and 'soldiers of the Matriarch' to get a rise out of Ukrainian soldiery. The soldiers are in turn prideful of their traditions and mildly embarassed - as anyone would be held to facts 300 years in their past (do Virginians still avoid work to hunt for gold, or do they all live on tobacco plantations?).
