The party finds out; either through investigation of the ruins or the goblins themselves; that a group of skeletons with eastern arms and armor had ransacked the village and took a stash of fireworks that the goblins stole from an old shipwreck. The party then makes it to this cave and finds it empty except for a half dozen skeletons. Further in past the skeletons is their leader, a skeletal samurai who fights the party in an attempt to defend his treasure. The treasure turns out to be a letter that reveals that secrets of the Kaijitsu family; the same family their good friend Ameiko who runs the Rusty Dragon inn belongs to; that lies in wait in the abandoned town of Brinewall to the northern boarder of Varisia. Ameiko along with several other important NPCs with a caravan north. It's recommended that GMs create encounters for the caravan trip north as it's essentially 3 weeks of travel with nothing in it. It's also recommended that GMs completely ignore caravan rules; they're not flushed out and they're not fun to run. The party and the caravan reaches the abandoned town of Brinewall where their friend Ameiko becomes possessed and is thrown into a coma; where the other NPCs agree to take care of her while the party explores the town and castle. The castle is a three floor behemoth of a dungeon populated by Dire Corbies, Troglodytes, and various other monsters all under the leadership of Kikonu, an Yamabushi Tengu Oni. The goal of exploring Brinewall Castle is to find the two keys to the vault; one of which is on the Yamabushi Tengu while the other is on a Half-Fiend Decapus that lives in the basement of Brinewall. Once the PCs enter the vault they find the Amatatsu Seal; one of the seals that cement authority to one of the ruling houses in Minkai of Tian Xia; as well as several visions that show that Ameiko Kaijitsu is the rightful heir to be ruler of Minkai and that they'll need to travel north to do so. Such ends the first book of six.

Can all sins be forgiven? The adventure is designed to kick-off a campaign, as it provides for an interesting way to get the party together. Instead of meeting at a tavern or being recruited by the local militia, each party member starts with a key to the NeMoren's vault, a key that was handed down by a friend or given as a gift for some good deed peformed in the past. The executor of the estate has gathered together all of the key-holders so that they could claim the contents of the vault. The vault can only be opened with all of the keys in unison. The vault is protected by a number of minor traps and tricks, but it also became the final resting place for the Baron's ex-lover, Lisette, and her brothers--all three of whom had attempted to blackmail the Baron. They were buried alive and are now undead. To complicate matters, a young umber hulk made its way to the vault, leaving some crude tunnels that were later exploited by hobgoblins coming from another surface entrance. The party will need to deal with the hobgoblins, the undead, the traps, and possibly the young umber hulk. There is a side-plot of poisoned groundwater in the nearby town that the party can also resolve by clearing out the undead and properly disposing of the putrid corpses leaking into the groundwater from the vault.
