Baldur's Gate: Dark Alliance II

=== Setting and characters ===
While the original game focused on three areas in the Sword Coast and Western Heartlands regions of the Faerûnian continent, the second game is predominately based in and around the city of Baldur's Gate itself.
The game features five main playable characters; Dorn Redbear, Ysuran Aundril, Borador Goldhand, Vhaidra Uoswiir and Allessia Faithhammer, each of whom has come to Baldur's Gate for different reasons. Dorn seeks fame and glory. Vhaidra has come looking for vengeance against those who have attempted to destroy her family. Ysuran is suffering from amnesia and has come in the hope of finding clues to his past. Borador comes for wealth, in order to release his clan from its debt to the drow. Allessia comes to spread the word of Helm and advance to become a high-ranking priest.

Story

The game begins by revealing that after jumping through the portal at the top of the Onyx Tower, Vahn, Kromlech and Adrianna are taken prisoner by the vampire Mordoc SeLanmere.
Meanwhile, outside Baldur's Gate, Dorn, Vhaidra, Ysuran, Borador and Allessia meet on the Trade Way, and learn that since the collapse of Xantam's Guild, the route has become increasingly dangerous due to the rise of the Red Fang Marauders, a goblin army who prey on travelers. After infiltrating a nearby Marauders cave, and freeing the caravan guard Randalla, the heroes head to Wayfork Village, a nearby fiefdom. There, they rescue the village from the Marauders and kill their hobgoblin leader, Harnak.
Upon entering Baldur's Gate, Randalla hires them to investigate a series of murders in the city. At Bloodmire Manor, they learn that Luvia Bloodmire has been combining the body parts of various creatures in an attempt to make a new species, and has been giving her creations to Lady Aragozia Firewind. Her first creation, Argesh, has set up the Hands of Glory, a thieves' guild faction of the Marauders. The heroes kill Argesh, crippling the Hands of Glory, and infiltrate the main base of the Marauders. There, they defeat but do not kill the Red Queen, leader of the Marauders. They follow her to Lady Arogazia's manor, and learn that Arogazia is a member of the Zhentarim, a criminal network intent on ruling Faerûn. She has been using the Marauders in an effort to bring back the Onyx Tower. Along with her associate Kharne (a former member of Xantham's Guild, presumed killed in the first game), Arogazia escapes from the heroes, revealing herself as the polymorphed form of the red Dragon, Aizagora.
Impressed with their efforts, Jherek, a member of the Harpers, requests that the heroes find four elemental objects. Meanwhile, the Zhentarim are also trying to attain the objects to reactivate the Onyx Tower. During their journey, the heroes encounter Sleyvas, the humanoid lizard who betrayed the protagonists at the end of Dark Alliance. He too is working for the Zhentarim, and the heroes kill him. After finding the four objects, each of the heroes pursues their own personal quest.
After killing the dragon Baragoth, the druid inside Dorn is awakened. Ysuran realizes his horrific past and his hate crimes against humans, determining not to worry about the past, but instead build a good name for himself in the future. Borador frees Gandam's Hold and reclaims the Goblinbreaker name for his clan, who begin working on new forges to free themselves from their debt to fey folk. Vhaidra travels to Cloud Peaks and gets her revenge on a murderous black elf who assisted in the fall of her family's house. Allessia frees the Church of Helm in Baldur's Gate from Goreth Vileback, a cleric of Cyric.
After the five return to town, Jherek enlists them for a journey to each of the Elemental Planes to activate the Elemental Foundations using the four objects they recovered. In each plane, they are attacked by the Zhentarim, who are in control of the Foundations. Luvia Bloodmire and Aizagora attack them, but are defeated. Upon returning from the final plane and speaking to Jherek, they are approached by Kharne. He tells them the Zhentarim no longer wish to reactivate the Onyx Tower, and that the Harpers and the Zhentarim have a common enemy: Mordoc SeLanmere. Mordoc believes he can use the Tower to bring about the downfall of Baldur's Gate, which will please his "allies in the east". His steward, Xanhast, interrogates Vahn, Adrianna and Kromlech, finding they know little of the larger scheme playing out. Kharne, Jherek and the five adventurers storm Mordoc's Keep of Pale Night. They rescue the trio of adventurers, forcing Mordoc to speed up his plans, and relocate the Onyx Tower into Baldur's Gate ahead of schedule.
Now called Mordoc's Gate, the entire population of the city are turned into zombies. The five adventurers attack the Tower, kill Xanhast, and attack Mordoc in the Elemental Plane of Shadows. After killing him, they destroy the Onyx Heart, supposedly destroying the Tower forever. This releases the citizens from their zombification, and led by Randalla, they thank the heroes for saving the city. Meanwhile, in a room with an Ancient Egyptian milieu, a servant tells a stone sarcophagus that Mordoc has failed and Baldur's Gate still stands. The sarcophagus says that Mordoc's failure will not interrupt his "sacred" mission, and orders his servant to prepare the army and ready his sun barge.
