[Excerpt from Encyclopaedia Populus: A Compendium of the Peoples, Personalities, and Practices of Ylan (5th ed.), by Miriam Busslewickett]
“Fhrey” refers to the House of the mighty elven king Malmondun Miralyith who, millenia ago, defeated and enslaved the kings of men and dwarves. The House of Fhrey remained at the head of the elven slave empire for centuries.
“Fhrey” is also commonly used to reference elves in general, regardless of their specific ancestry.
