 Berg-Önundr gathered a company of men to capture Egil, but was killed in his attempt to do so.During his escape from Norway, Egil killed Rögnvald Eriksson, Erik's son.He then cursed Erik and Gunnhild by setting a horse's head on a pole in a shamanic ritual (the pillar was a "níðstöng" or "níð-pole"; níð translates, roughly, to 'scorn' or 'curse'.)
