Heat-Eater

The Heat-Eater first emerges in The Name of the Wind as a clever makeshift sygaldry device, ingeniously scratched by Kvothe onto a charred shingle using thumbnail-carved runes of ule, doch, and pesin to quench heat through sympathetic linking, proving effective even underwater. Across the series, it symbolizes Kvothe's resourceful ingenuity in binding and manipulating elemental forces amid dire circumstances. Though its appearances remain sparse beyond its debut, it underscores the evolving mastery of naming and sympathy that defines the chronicle's arcane progression.
