G'Kar and Stasi journey to the Harkenwood near Marshglen, searching for the young lord Erathon and a party that set off to protect the town but disappeared a week ago. The people of Marshglen report raids by monsters and are moving to the walls of Rathmore and safety, abandoning their villages. The rest of the party patrols the woods north and south of Marshglen, looking for monsters and signs of Earthon's party.
They head east and find a lizardfolk village that Erathon's men sacked. The lizardfolk had been raiding Marshglen so he killed all their warriors. The rest of them were clearing out the town and heading north.
Continuing east they found a hag living among some ruins with several scarecrow constructs doing her bidding. She gave them a map of the faterift and told them Erathon headed east and is probably dead. She and her three sisters were kicked out of the Faterift vale to the east by Darcayn and her followers.
They rest in the ruins and fight off a venom eye basilisk. The next morning they set off to the Tower of Ashes, the first of three structures built in the Faterift, a giant tear in the fabric of time and space. The Tower of Ashes is built on a great portal to the elemental chaos and a pillar of flame juts out of the top of it. They fight off several fire bats and their master, a wicked pyromancer, but G'kar kills the wizard with his black magic longsword.
They rest again at the hag's ruin and travel east again the next day back through the burned woods to the Tower of Ashes. Inside they find some astronomy books, charts and a telescope which they collect. They also find several of Erathon's party burned to death in the tower.
They continue on to the Tower of Skulls, built on a portal to the Shadowfell, in the middle of some red mud flats. They fight several zombies, including a rotwing and an undead ettin. They defeat the creatures and rest then enter the tower, made entirely of bones and skulls. Inside they fight the undead ettin again and a ghoul ally. In the heart of the tower they find a cocoon dripping acid into an urn. They perturb the cocoon and a teifling necromancer escapes and summons an ochre jelly to attack them. They fight desperately against the beast but prevail in the end.
Resting in the Tower of Skulls they find more texts and learn that Darcayn plans to perform a ritual at midnight during a special lunar eclipse (just hours from the time they read the text). During the ritual she will sacrifice eight elven maids to Lolth to gain eternal life.
They decide to rest and gather their strength rather than rushing ahead in their weakened state, though they know that some of the maids may die in the ritual if they are too late. They arrive in a field of ruins near the Tower of Sorrow just before midnight as the eclipse is underway. In the ruins they find a terrible gibbering mouther born of the rift to the Far Realm that the Tower of Sorrow is built on. The fleshy mass of eyes and mouths spews acid on them, but they fight past the thing that twists the landscape wherever it passes.
Moving to the gate of the Tower of Sorrow, Stasi squeezes through a rusty portcullis, silences the winch and door with magic, then opens the door for G'Kar. On the battlements they fight a party of four evil humans armed with magic weapons and armor and defeat them.
Inside the Tower of Sorrow they find Darcayn working her ritual. Two of the eight maids have already been slain. She is using a holy avenger stolen from Erathon for her profane ritual to achieve immortality. Darcayn is an evil artificer called a fleshweaver and has grafted several spiderlike magic limbs to her body, which she uses to attack them when they interrupt her ritual. The battle is long and bloody but G'Kar eventually takes down the chaotic arcanist.
In the dungeons they find Earthon's body, which they return along with his magic sword to Baron Pernod in Therund. They also return the six surviving maids to their kin in Rathmore on the journey home. They are rewarded with gold and titles of honor in Pernod's court. Attempts to resurrect Erathon are unsuccessful. All presume that Darcayn somehow stole his soul or it was lost somewhere in the Faterift Vale. Stasi and G'Kar carry his body in the funeral procession to be burned in a pyre in the city square.
