This chapter overhauls Van Richten's Tower:
The Shadow of Khazan. The spirit of Khazan—archmage, lich, and architect of this tower—cannot find rest. Punished and humiliated by the Dark Powers, the lich has been reduced to a boneclaw and imprisoned in a shadowy demiplanar prison overlapping the tower. As the adventurers explore the tower's magic, they risk releasing Khazan himself.
In the Wake of Defeat. The chapter's two Special Events—Ezmerelda's Retreat and Pack Attack—have been combined into a more streamlined and worthwhile event.
Dramatis Personae. A handy guide detailing all characters featured in this chapter of the campaign, with advice and variants.
Areas of Note. An in-depth overhaul to the tower's barren areas, replete with new and better flavor, new lore, and new loot.
DM Notes. Notes including but not limited to spicing up the region with valuable roleplay with select NPCs.
Magic Item Descriptions. Save yourself the time of digging through the Dungeon Master's Guide to determine how the magic items in this chapter work.
Monster Stats. Time is precious, and matters all the more in combat. Appendix B has the statistics for the NPCs used in this chapter!
