Ascent Through the Flue

The rush of sub-zero air came through the split stone with the force of an unlatched sluice. A loose slate had slipped somewhere high along the citadel's outer spine, its clatter lost to the whistling draft that poured through the freshly opened seam in the pantry masonry. Over the toes of Lyra’s boots, the pale dust of crumbled mortar stirred, then froze hard where condensation skimmed the flagstones. Beside her, Lord Kaelen shifted his weight without scraping sole to rock, moving until the heavy dark velvet of his doublet cut between her shoulder and the worst of the incoming gale.

Beneath her bodice, the hearth-anchor answered the chill before Lyra could still it. The ancient relic flared in rhythm with her quickening heartbeat, throwing a sudden, deep thrum of heat through the fabric of her shift. It did not cast enough glare through her gown to betray them through the warped gap in the door, but on the stones between her feet and Kaelen’s, the encroaching frost turned glassy, dissolved into beads of dark water, and vanished into the porous granite. Her skin burned with a fevered flush against the bitter draft, the bond between them thrumming in time with the hidden mechanism.

She caught her balance against his arm as the floor slicked beneath them. His calloused hand slid down to find the curve of her waist, drawing her firmly against his chest to anchor their footing against the masonry. Lyra's fingers locked into his free hand, their grips knotting together within the fold of his cloak in a quiet, desperate effort to share warmth and stay upright. Through the thick layers of wool and velvet, the steady, rhythmic pulse of the anchor pushed back the winter air, carving out a pocket of stubborn heat within the stone hollow.

"Still," Kaelen murmured, the warning scarcely more than a movement of his lips against her temple, his dark curls stirred by the downdraft.

Out in the scullery, the quiet broke. Morvath’s heavy boots dragged once across the floor, the sound dull and deliberate, accompanied by the dry click of his brass-banded ledger as the steward shifted his grip. The stooped fae was moving toward the pantry threshold, his milky eyes searching the dim perimeter of the kitchen. With the doorframe gouged and warped from years of damp, the half-inch gap along the jamb was wide enough for anyone outside to catch the dark texture of velvet or the gleam of an eye if the steward raised his tallow candle.

Kaelen did not look back toward the pantry door. His focus remained fixed on the dark, jagged fissure splitting the pantry wall. What had appeared as an unstable crack opened into a vertical shaft—the citadel's hollow spine, a soot-choked winter flue long since turned into an icy conduit by the fortress's collapsing wards. Frost coated the protruding granite headers inside the opening, forming narrow, treacherous ledges that rose into the fortress's unmapped heights.

He met Lyra’s eyes and gave a single, decisive nod toward the gap. Waiting in the alcove was over; the stolen registry parchment remained secure inside her sleeve, but discovery by Morvath would bring Commander Varis's enforcers down upon them before they could reach the lower canals. Releasing her hand only long enough to find a secure purchase, Kaelen set his boot onto the first ice-rimmed foothold within the chimney conduit, testing the stone before extending his arm down to guide her into the cold ascent.
