It is clear that Perenolde must be killed, his foulness removed from the world. His manor lies a ways to the north of here, on the shores of Lordamere Lake. Do your duty, $n, then retrieve the pendant that the Warchief desires, and return here.
Kill Lord Aliden Perenolde and ask his mistress, Elysa, about Taretha's pendant.
Return to Elysa at The Uplands in Alterac Mountains.
