Doorm

In Tennyson, a lord whose lands Geraint and Enide entered during their journey. His vassals called him 'the Bull'.

He came across an unconscious Geraint and a destitute Enide. Bringing them to his castle, he tried to convince Enide that Geraint was dead and that she should accept his favors. When she refused, he beat her. Her screams awakened Geraint, who jumped up and slew Doorm.

Doorm is known in Chrétien’s Erec as Oringle and in the Welsh Geraint as Limors.
