Regardless, region C has some pretty cool stuff behind some pretty nasty locks. For example, Aslur'thyn, the spectre, is behind 4 locks (DC 30, 35, 35, 40) which each have some fairly nasty traps and a mass reset if one of the Open Lock checks is failed by 10 or more. Shame. I liked how Hussar rewrote this a bit so that his party could actually FIGHT Aslur'thyn. After all, spectres are just too nasty and deadly to not use.
