The Lost Aethelgard: the Moon (Vol. 65)

Summary

In a high-altitude fortress carved from solid mountain ice, a silent archivist who can hear the whispers of old books discovers a mysterious letter delivered by a bird made of pure mist that could reveal a treasonous plot at the heart of the royal court. Pursued by a silent, phantom entity that stalks the coastal fog, they must race against time before the crystal spires of the capital city begin to fracture.
