The Royal House of Riftgard Script was the written language of the Pure Ferrets at Riftgard. All of the objects produced in Riftgard were inscribed with R.H.O.R. in the Riftgard script. The system was also used to write maps, clues, and other documents. According to the hamster Mokug, only pure ferrets could read the script. However, it was not a separate language but a different writing system. Sagaxus and his friends discovered several items with the R.H.O.R. inscription on them, and the boat Triss sailed away on was full of items with the script.
