The alliance work begins in earnest and every alliance comes with a code attached. The Saxon kingdoms have their own honor systems, their own debts and obligations, and Eivor has to learn to read them without abandoning her own. It is a session of translation as much as combat.

What makes Valhalla's middle section work is that honor is never frictionless. It binds and slows and sometimes demands the wrong thing. Eivor carries it anyway. Not because she is noble but because she knows what people become when they put it down.
