The Chronicles of Anglarthea - The Legend of the Sages Stone
The Feiger, is the realm between realms. It a place of fairies and other such creatures. During the Age of Darkness Laenacus’s armies tried to enter this realm with such ferocity that the fabric between the two realities became ripped, allowing creatures the evolved in the Feiger to pass through the the mortal realm. This has also happened where magic has been used in in such excess it has weakened the barriers between the lands and altered the realms. Two of the most common places to see a creature of the Feiger are on the The Shattered Islands of in Lumene though they have migrated to other areas as well.
