Deep in the elven forests of Myereth, ancient rowan trees spread white boughs above a sacred site. Pillars of stone twist like some strange form of vine, curling among the branches and reflecting the light of a silvery moon. The forest is silent, and beautiful, protected since the dawn of time by a powerful Unicorn. The elven forest of Myereth is well known throughout the world as a safe haven of good and peace, a place where evil cannot stand to enter and where the trees weep healing tears upon those injured within its boundaries. Any player character elves know of the forest, its healing properties, and its legendary beauty. They may have heard of it as a legend, or they may have visited its mystic shrine when they were children, brought along on a pilgrimage by other elves. But something has gone terribly wrong. Refugees from Myereth, terrified and confused, are flooding into other elven cities. They speak of a great evil that has conquered the forest, one that has killed the body of the immortal Unicorn and tainted its spirit. Myereth runs with blood, they say, and the once-powerful rowan trees have begun to wither and die. In the center of the Rowan Grove, the bloodied bodies of the last elven warriors of Myereth lie scattered and broken. Those responsible call themselves the Servants of the Blood Moon, and they are led by a dark-robed sorcerer. The surviving elves do not know this evil man — all but one of those who fought against the Servants died — but they know that the sorcerer calls himself Tamarat. He has butchered the Unicorn, the spirit of the forest. The Myereth, and the elves, are dying.

The last of his line, Baron Paytro NeMoren has left his dark secret sealed for decades in the family's underground vault. Now, years after his death, a group of stalwart heroes has gathered according to the baron's final wishes. At last, the seal will be broken and the secrets of the vault revealed. 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.

A goblin warband has found the secret tunnel which leads from the dwarven keep of Hearth-Home to the nearby hills. The tunnel is intended to be a means of escape if the keep ever falls to attackers, but now it has provided goblins with an easy way into the Underkeep. So far, the goblins have confined their attentions to the various underground rooms that make up the Underkeep, but sooner or later they will find a way to the surface. They pose a serious threat to Hearth-Home - the goblins must be cleared out of the Underkeep so this breach in security can be repaired before the orcs hear of it and overrun the dwarven keep.
