House Lune ivory box

The House Lune ivory box first appears in Iron Gold as a modest container of family relics, yet it quickly becomes a vessel of dynastic memory and political consequence. Across the series it transforms from a private keepsake into a symbol of legitimacy, its sigils and contents invoked whenever the Lune claim to sovereignty is challenged or reaffirmed. By the later books the box is treated less as an object and more as an heirloom talisman whose opening or sealing can sway alliances and settle questions of succession.
