(Gryffins, Gryffans, Gryfons)
Why Gryphon? The Gryphon is a fabulous creature, with the body of a lion and the wings and beak of an eagle. It was chosen as our logo because it combines the courage to fight when required and the ability to see clearly what lies beneath. It has many different representations (and spellings) and a colourful history which is well documented at The Gryphon's Eerie. http://www.gryphonguild.org/gryphonpages/
The next best Gryphon picture, after our logo, is from 1777
There are also many superficially similar creatures. The closest relative is the Opinicus, differentiated by the head of an eagle, forepaws of a lion and a stunted tail.
