Leyline Atlas

This palm-sized atlas is bound in midnight-blue dragonhide and clasped with tarnished silver. Its pages are made from thin sheets of pearlescent mineral that shift beneath the touch, displaying maps of places both familiar and impossibly distant. Fine golden lines thread across every page, forming a constantly moving network of ley currents. When opened, the atlas emits a faint chime like glass struck beneath the earth, and the nearest known ley current brightens in response to the reader's presence.
