Wow, you just unlocked a core memory for me. Okay, so the absolute pillars are Kest and Tricia, the siblings at the heart of it. The whole story spins on their bond—Kest, who’s all duty and this quiet, simmering anger about their family's legacy, and Tricia, who’s trying to find a softer path but keeps getting pulled into the fight. They're the dual protagonists, no question.
Then you’ve got the old mentor, Garret. He’s the one who knows the real history of the ‘path’ they’re on, and he’s got his own ghosts. His dynamic with Kest is this great push-pull of respect and rebellion. The antagonist, Lord Maquin, feels a bit one-note as the greedy noble, but his captain, Elara, is way more interesting. She’s not evil, just on the other side, and her clashes with Tricia add a lot of grey area. Oh, and the smith, Bren. Minor character, but he shows up just often enough with a warm meal or a sharp blade to feel essential.
