The infidel queen of Tribalibot, and its cities of Thabronit and Thasme.

She was fascinated with stories of the Grail, and she sent two of her subjects - Cundrie the Sorceress and Malcreatiure - to Anfortas, the Grail King, as servants.

Later, she fell in love with Feirefiz, Percevalís half brother, and gave him her lands in exchange for his devoted service. He eventually cast off her love, however, in favor of the Grail Maiden Repanse de Schoye, causing Secundille to die of heartbreak.
