Horns of Nez'ra

Many years ago, the Horns of Nez'ra were stolen from Ravenholdt manor. Across continents and oceans I have searched, only to discover that these insignificant beasts have had it in their possession all along. Slay every Blackrock orc you cross until the Horns of Nez'ra are recovered. Should you recover the horns, find me in Lakeshire. Do this for me and your name shall be known to Ravenholdt, <name>.
