Original: In his drugged state, Siegfried offers to win a wife for Gunther, who tells him about BrÃ 1\/4 nnhilde and the magic fire which only a fearless person can cross. They swear blood-brotherhood (Hagen holds the drinking horn in which they mix their blood, but he does not join in the oath) and leave for BrÃ 1\/4 nnhilde's rock.
Simplified: Hagen tells him about BrÃ 1\/4 nnhilde on the rock.
