Son of Bedwyr, brother of lady Eneuawc (Eneuawg), and one of Arthur's warriors. He held the position of chamberlain and guarded Arthur's bed.

He accompanied Arthur on an adventure to the cave of the Black Hag in the Valley of Distress. Amren was beaten senseless by the hag.

Amren's name later passed into the Arthurian cycle as the son of Bedivere.
