Gates of Oldtown: the Ancient Oak (Vol. 47)

Summary

In an underground labyrinth where time flows backward, a exiled princess hiding in plain sight as a tavern maid discovers a velvet black thread that absorbs all light around it that could reveal a treasonous plot at the heart of the royal court. Pursued by a corrupt grand inquisitor obsessed with absolute control, they must race against time before the stars align to form the shape of the dragon's eye.
