unseelie

After Tristran's death, there were those who claimed that he was a member of the Fellowship of the Castle, and was instrumental in breaking the power of the Unseelie Court.

There was a war in the East, an Unseelie king with a lot of territory and no desire to bend his knee to the High King.

Maybe you’ll return to warring with smaller Seelie and Unseelie Courts.

I see Queen Annet of the southmost Unseelie Court, the Court of Moths, signal to her courtiers to leave the hall.

A motley group still fills the hall: glittering Seelie and terrifying Unseelie; the wild fey that seldom leave their hills, rivers, or grave mounds; goblins and hags; pixies and phookas.
