Radim is the wheelwright in the smithy for the village of Klucz. There is little description of him during his brief appearance in the short story Droga, z której się nie wraca (included in the Coś się kończy, coś się zaczyna (Something Ends, Something Begins collection), besides him wearing working overalls and boots. Radim is killed when he is stabbed through the stomach with a spear by one of the vrans from Koshchey's Men.
He also appears in the graphic novel Droga bez powrotu, based upon the Droga, z której się nie wraca short story. In this version, Radim is portrayed as having dark brown hair and a big nose. His death remains unchanged.
