Kaysera

Kaysera emerges in the second book of The Kingkiller Chronicle as a legendary grey metal blade mounted on a dark wood board behind the bar in a tavern, ominously dubbed the poet-killer. Distinct from Kvothe's own sword Caesura, it hints at a dark history tied to violence against poets, evoking the series' themes of naming, power, and lethal artistry. Though its full backstory remains shrouded across the known volumes, Kaysera stands as a chilling artifact underscoring the perils faced by performers in this richly imagined world.
