The Forgotten Realms™…
Mafain Aelfpath: Created thousands of years ago, the elves of the forgotten realms managed to tunnel their way into it, while researching Mythals of the Forgotten Realms. It is a weak Aelfpath, the Laey thread is not well set – it is fading back into the Feywilds slowly. It is unknown how old the path is, but a great deal of it has become a Broken Road.
