"There are several notes/diary entries in the quest, including one small easter egg involving a body of a Drothmeri soldier you'll find near the outer walls of the ruins. The body is holding a quill and there is An Undelivered Letter next to him containing his final thoughts, including his realization that Drothan is a madman."
If anyone can give me the location or a pic of it so I can use landmarks as reference that would be much appreciated I suppose Its just one of the few things I haven't found and is driving me crazy.
Any help is appreciated.
