Aedyran is the language of the Aedyr and is spoken in the Aedyr Empire, the Free Palatinate of Dyrwood, and the Penitential Regency of Readceras. Aedyran is derived from the now archaic dialect Hylspeak and Eld Aedyran.
Aedyrans, Readcerans, and Dyrwoodans used to speak a language called Eld Aedyran that is an analogue for Old English/Anglo-Saxon, Old Frisian, bits of Icelandic, and Scots (for Hylspeak, a more contemporary version). j, q, v, and z do not appear in their words and names, though the /v/ sound is found in medial and terminal f. E.g. "Wyflan" is pronounced "WEE-vlan".
