What is "charudes"

The Charudes or Harudes were a Germanic group first mentioned by Julius Caesar as one of the tribes who had followed Ariovistus across the Rhine. While Tacitus' Germania makes no mention of them, Ptolemy's Geographia locates the Charudes (Χαροῦδες) on the east coast of the Cimbrian peninsula (see Hardsyssel). Their name suggests that they may have at one point settled in Hardanger in the county of Hordaland, Western Norway.
