Speak with Shadowmage Vivian Lagrave.
Vivian Lagrave sent me word from Kargath, in the Badlands. Through her studies, she believes there is an ancient text within Blackrock Spire that would benefit our research. To confirm this, she will need someone to extract the text from the spire. No easy task.
