Odd question but I think it’s fun to think about. I’m not super up to date on Trek lore but I feel like there’d be a big divide between Odium devotees and those who think he’d be dishonorable. Some Odium upped Klingons would be pretty terrifying. Can you imagine a Klingon on red mist? Fuck me that’d be scary since they pretty much already have a built in red mist.
I don’t think the Alethi would have won the war on the Shattered Plains
Definitely not. An army of highly skilled warriors whose greatest desire is to die valorously in battle hopped up on pure passion/rage. You’d need some high grade weaponry to stop them.
