Milea's army wasn't just repelled, it was utterly destroyed every time they moved one inch inside the Kingdom's territory. To make matters worse, Thrud didn't leave the command of her troops to one of her generals like the Royals did.
She led them herself, charging into battle first.
Her exploits were broadcasted via the Kingdom's interlink, growing her reputation with each skirmish. To her citizens, she wasn't just an invader, she was a hero that protected their country, putting her life at risk and fighting on the frontlines.
It boosted the morale of her armies and her territories while also dispiriting the enemy's. Not only were the members of the Royal army and the Association scared by the prowess that Thrud's army showed.
They also secretly started to wonder if with her as their new Queen, the Kingdom might be able to reconquer the territories that had been lost after Valeron's death and return to its former glory.
