When Leigamar scheduled a tournament, Quebeleplus quarreled with her sister, Flursenesphin, over the prowess of the latter’s beau, Fiers of Arramis. To get back at her sister, Quebeleplus begged Gawaine to defeat Fiers in combat. Gawaine complied and delighted the little girl.
The same character appears in Wolfram’s Parzival as Obilot.
