Dear Sir,

I recently began paying homage to Grumbar when I arrived in Sanctuary. His solid, consistent teachings seem to be what is needed in this environment, and I look forward to bowing down before him again when I am next in the vicinity of His holy shrine.

I am an amateur spelunker and geologist, and I am presented with a rare opportunity now that I have made my home in Sanctuary. On the surface, I read about an arcanist named Zabar who researched extensively with a mineral called Harmonium, a substance that is found only in the Underdark. Though the substance does not have any practical applications that I know of, I would like to glorify Grumbar by finding and researching a sample of Harmonium. Truly, He would be pleased that his followers work to understand the great mysteries of His rocky domain. Would any of the faithful know of any samples or deposits in the area?

I look forward to speaking with you soon on this topic.

Sincerely,

Lucius Foxmantle Crone, Room Two
