Not Meant to Know

Approach, |c. Here I am, and here I stay. My purpose is clear, and I am bound to it for eternity. Not so, you. Not yet, at least. You can come and go at will, so long as you are not impeded by those who are mightier. There is one in the Undercroft named Gromias. Once a soldier of the Empire, he is now an insane, tortured traveler. Much he's seen, though he lacks the ability to express the anguish of his broken mind. His speech is a mix of gibberish and tortured shrieks. Go to Gromias and touch him with this Shard. It will take his pain from him ... as well as his mind, his memories, his sense of self. Nothing will remain, but for the husk of his body. Return to me with the Gromias-Empowered Shard, and I will reward you well.

Travel south, into the Undercroft. Search for and find Gromias. Use the Dull Shard upon him to capture his soul essence. When the Dull Shard has ended Gromias' pain by capturing the essence of his mind, speak with him to ensure nothing of the man remains.
