One day this great man of valor was called onward to continue his battle for freedom and goodness on a higher plane of existence. Leaving the responsibilities of rulership to his faithful overseer, he donned his magical shield, helm, and sword and traveled to the Holy Maountain of Anduin to meet his destiny.

Although the three parties sent before you had not returned, ridding the of the land of the mage seemed worth any risk, and you eagerly set out on your quest. Now, standing before the defiled mountain, you wonder if perhaps you were too hasty.

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.
