Greetings, Mephisto,

I must say, I take umbrage at your supposition that the Codex is a "book
of lies." As most scholars who have been following my studies know, I
have already written a book of lies. I have titled it, "The Book of
Truths and Lies" and it can be found right next to my usual resting spot
in the Obelisk. Read my book and it becomes plain to see that my work is
far superior to the Codex.

In Darkness,
Teneb, Doctor of Theoretical Planar Physics
