First, let me note that this is an awesome delve - one of the best IMHO, and far better than many of the carelessly designed delves even in the main game. Great work! Same goes to some other delves in Summerset, too. To those who did not play it yet - I'll try not to spoiler.
However, in the last room you enter when finishing Ullicetas quest (the secret room of a well-known necromancer), I found a disturbingly large number of "Argonian Maid"-related books in those monstrously huge book shelves, making me wonder what exactly Mannimarco *really* has been researching the whole time

are there maybe even some euphemisms in the main quest that I missed?
