Evren

"Bran became king 'cause he killed the dragon Evren."

Evren was a dragon active on Skellige in the 13th century. To prove himself worthy of the crown, Bran Tuirseach killed Evren.

In, the story was recounted by Otrygg an Hindar to Blueboy Lugos and Halbjorn during Bran's funeral feast at Kaer Trolde citadel, with the trio wondering how to surpass such a feat.
