In the author's words, "this is a side trip in the Tempus Irae universe, and may be assumed to take place at any reasonable point during the original storyline." One level, or two if you count the setup intro. Mapmaking is very high quality, and the story is well-written. There are a couple of places where monster triggers could have been placed better... but that's a nitpick, suggesting that only nits are wrong with this one. Download it today - it's a great romp!
