Endorion is a premier Bulgarian website dedicated to the intricate universe created by J.R.R. Tolkien. Established in 1999, it began as the first online resource for Tolkien enthusiasts in Bulgaria, rapidly gaining traction among fans. Over the years, Endorion has united multiple platforms, merging the rich resources of its predecessors, "Tolkien Online" and "Valacuent," to become the leading source of information on Tolkien's works in the Bulgarian language.

The site features a wealth of materials, from in-depth analyses and translations of Tolkien's writings to a collection of humor and blogs, all designed to foster a vibrant community of Tolkien lovers. The term "Endorion" itself is taken from Tolkien's invented Elvish language, meaning "For Middle-earth," reflecting its mission to provide comprehensive insights into the beloved worlds of "The Hobbit" and "The Lord of the Rings." Through ongoing contributions from dedicated fans and scholars, Endorion continues to be a vital hub for everything Tolkien-related in Bulgaria.
