The strength economy is in shambles.

some soft bloodweave(?) sry if it was too boring xD

If you do the Karlach origin and you have romanced her, she will urge Karlach to return to Avernus. If Karlach chooses not to, Minthara will cry. This is the only scene in the game where Minthara cries and shows that level of emotional vulnerability. Lol, she didn't even cry when she was being tortured in Moonrise and thought she was gonna die! She tries to persuade Karlach by basically saying, "I'm going to personally throw hands with Zariel regardless on whether or not you're with me, so you may as well come with me." That vengence paladin in her is really shining through. And Minthara is a paladin of her word. Even if Karlach does choose not to return and dies, and enraged and heartbroken Minthara will walk right into Hell and invent a new flame so hot not even Zariel can resist the heat.

If you do the Karlach origin in which you go to Avernus but do not romance Minthara, she will be excited to see Karlach at the reunion party alive and happy. She also says that once she reclaims her house, she has every intention of joining Karlach in Avernus and she does this completely unprompted! Karlach does not even ask and Minthara is just offering her an army once she has one, and she will provide it free of charge. Karlach can ask Minthara why she's doing all of this. Minthara kind of not so subtly admits that she's in love with Karlach, but, of course, won't use the words "love" and she dances around it.

Romanced or not, Minthara is willing to go head first into Avernus on Karlachs behalf to demolish Zariel. Do you have any idea how huge that is? Minthara has been nothing but power hungry the entire game and is constantly clawing to get more. But in this moment, she is putting all desire for power on furlough just for Karlach. She is going to wage a war against Zarial and all of Avernus for the life of just one person, a person who might still die in the end. If Karlach does not romance Minthara, she is still putting her own ambition and desire for power on hold to help Karlach in which she'd gain no benefit other than Karlach being alive.

You cannot convince me that Minthara isn't canonically in love with Karlach.
