Tomb of Annihilation
Chaos descends as death looms over the continent of Xen'drik and perhaps all over Eberron. A mysterious wasting disease is affecting many seasoned adventurers. If all the adventurers perish, who will slay the goblins? Who will loot the tombs? Who will rid the basements of rats? It's up to the players to keep the world order in check and figure out what is killing adventurers before they too succumb to it.
