Erdin

Brother of Isolde of the White Hands in the Serbo-Russian Povest’ o Tryshchane, slain by Tristan (Tristram) at a tournament in Baroh.

Tristan was badly wounded during the fight and may or may not have recovered at the hands of Isolde, Mark’s wife.

His name bears a resemblance to Kahedin, Isolde of the White Hands’ brother in other sources.
