Morvran

Morvran is an elven NPC that makes a brief appearance in the game after you exit the Underground Pass in Regicide.

With the help of Essyllt, he slays Idris.

The word Morvran is made up of the Middle Welsh words mawr, meaning "big", and brân, meaning "crow". The name is parallel to the Celtic spelling, Morfran, with only the f changed to a v. The Older Welsh usage, is likely due to Jagex's usual use of the Welsh language in most of the Elven names in the game. Morvran is often depicted in Welsh Mythology as a dark, demon-like character that is very ugly.
