“In the mid-thirteenth century several of the Raven King’s enemies were attempting to form an alliance against him. Most of its members were known to him: the King of France was one, the King of Scotland another, and there were several disaffected fairies who gave themselves grandiose titles and who may or may not, have governed the vast territories they claimed. There were also other personages more mysterious, but even greater. The Raven King had, for the most of his reign, been on good terms with most angles and demons, but now it was rumored that he had quarreled with two: Zadkiel who governed mercy and Alrinach who governed shipwrecks.”
Jonathan Strange & Mr Norrell, Susanna Clarke
There is a new Jonathan Strange & Mr Norrell wiki, which I have linked above. Once I have completed my first reading of Jonathan Strange & Mr Norrell, I would like to go back and pick out all the references of the Raven King and add them to the wiki.
