Have you seen the ruins of Ameth'Aran? If not, you will find them on the eastern side of the main road, some ways to the south. Once they were the home of many powerful Highborne, now they are a testament to the destruction their dabblings produced.
I have been told by the Sentinels that the spirits of the Highborne persist, and that they wield their ancient magical implements. Those relics must be appropriated, so that we might destroy them.
Though it is surely a figment of my imagination, I feel as though I can almost feel the taint of foul Highborne magic upon them. I will have these destroyed, so that their long dormant evil might never be released again.
