Lybius Desonus

'Fair Unknown One'
Lybeus Desconnus

An illegitimate son of Gawaine (his mother kept his ancestry a secret) and a knight in Arthur's court.

He was sent to rescue the Lady of Sinadone, which he did, accompanying the damsel Ellen.

This character is identical with Guinglain, Lybius being his nickname; Lybius Desconus means 'Fair Unknown One'.
