Klucz (Polish for "Key") is a village located near the area where the Yaruga forks off into the Ina. The villagers from Klucz joined forces with peasants from two neighbouring villages, Kaczan and Porog, to fight the koshchey. The settlement is featured in both the short story Droga, z której się nie wraca (included in the Coś się kończy, coś się zaczyna (Something Ends, Something Begins collection), and the graphic novel Droga bez powrotu. Both titles translate roughly to "A Road with no Return".
