Gibel

A fairy land visited by Arthur’s Sir Jaufré after he fell through an enchanted fountain. The land was attacked by a horrid monster called Felon of Albarua, but Jaufré killed it. The lady of Gibel rewarded Jaufré with a banquet.

Montgibel is Morgan le Fay’s residence in some romances, and the lady of Gibel is probably identical to Morgan.
