A lot of icons used in this wiki (but not in the restricted groups) where initially published by the Magellan development team under the GPL. Therefore the most unrestricted pages will be published under the GFDL. This includes the groups Eressea, Welt12, Welt13, Welt14 and EresseaBegriffe. Other groups like PovRay or VoIP aren't published under the GFDL.
