Radim was 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 Something Ends, Something Begins), besides him wearing working overalls and boots. Radim was killed when he was 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 was portrayed as having dark brown hair and a big nose. His death remained unchanged.
