| Uniqueness | Arvorec is (in Ill Bethisad) virtually unique, the only surviving P-Celtic language. |
| Language Sources | The language is derived from Gaulish. |
| Design Principles | To have a "feel" somewhere between Welsh, Cornish and Breton, to be immediately identifiable as "Celtic" and to my personal aesthetic principles. |
