Sluagh

 

The Sluagh (slü-ah) are Elves of the Shimmering Haven that long ago achieved Lichdom. They have been locked in battle with the Archfey ever since the Feywild portals were ripped open. Like Archfey, they are not necessarily evil, their motivations may seem like it sometimes, but that's usually because they span centuries, making it hard for most to understand them.
