The Frozen Legion

Tamsin Prowse knelt three times before the Binding Oath, and three times it passed over her as though she were invisible. Now she copies supply tallies in a dusty office while the Wall of Gates—eight colossal fortress-doors separating the living lands from a frozen waste—begins to crack. The Fourth Gate has opened from within, its garrison frozen mid-salute, and frost-script scrawled across the stone carries a demand only Tamsin can read: a two-thousand-year-old promise is coming due, and the price of breaking it may be everything the Confederacy has built on lies.
