Synopsis: A swamp village is plagued by swarms of insects; several villagers have died from it. It turns out that the local herbalist is actually a vampire who takes the form of a swarm of mosquitoes. Talk to villagers and get rumors, visit the herbalist, suffer through some dreams, get ambushed by the herbalists minions, chase him into the basement to kill him and rescue the villagers. The mosquito vampire and, maybe, the role play involved in convincing the villagers to dig up the graveyard (to find empty coffins filled with sand!) should be fun. The rest of this is pretty simple.

This is Part 1 of an adventure designed for characters of the 20th to 21st level About 200 years ago a horrific massacre took place on the remote Soron island of Heikun. For months, the deranged and corrupt priests had sought to create a race of hybrid Snake-Men...a race which they believed once existed in Soro. They kidnapped folk from surrounding villages and took them back to their temple. There they performed unspeakable rites and experiments. Sensing their debasement, the dark spirits of the mountains called to the priests in their dreams, luring them down into the vast sub-levels beneath the Pyramid. Somewhere in the cavernous depths they were touched by an eternal evil and given horrific new forms. The deformed priest-things of Heikun crawled back to the surface, systematically destroying all living creatures in their path, including the city's hapless, ineffective leader: the inbred boy-king Yusef.

Listen up! You're in my dungeon now, Morty! On Earth C-141, I'm a LEGENDARY D&D adventure writer! When people think of impossibly difficult dungeons or winding, labyrinthine maps, those things ain't Gygaxian - they're SANCHEZIAN! I do whatever I want over there, and they eat it up! I'm a celebrity Dungeon Master there, too! My livestreamed show, Cynical Troll, gets a billion views a day! It seemed a little selfish to contain all that GREATNESS to a single dimension, so I lifted one of the all-time favorite Sanchezian adventures and snuck it back here to dimension C-132. (Usually that kind of s**t is frowned upon, but it's just a D&D adventure. We're not exactly violating the Prime Directive or whatever.) This is a good old-fashioned dungeon crawl for a party of 1st-level adventurers, whose character sheets in this box should also contain. They'll probably reach 3rd level by the end of it. So here it is. This adventure brought peace to a warring galaxy. What did you ever do? Oh, you picked up this adventure? Good start. And awaaaay we go!
