The Tolkien D20 project is a page to present and download for free the pdf project dedicated to adapt J.R.R. Tolkien’s world to D&D 3.5 rules.
The work takes into account how a Middle Earth based campaign differs from a standard D&D campaign: magic rules and classes were updated, enabling a description of the main characters of Tolkien’s opera – from the might Valars to the Istari, from Gothmog and Ancalagon to Fingolfin and Luthien, down to the hobbits – using a D&D 3.5 template.
