The title of the letter is 'Riches beyond imagining,' with Cassia repeating the phrase at the end. Unfortunately, Cassia's brother disappeared when investigating the ruins, and she wants someone of the Dragonborn's caliber to find him.
In it, a character called Cassia begs for the player to journey to this ruin. Written in a stylish cursive, the letter describes The Forgotten City buried deep within Dwarven ruins. The Dovahkiin, resident quest jockey of Skyrim, receives a letter by courier.
