Walkthrough

This quest is a variant of  Resolve the Abduction. It can be initiated when reaching Moonrise Towers and returning the Nightsong to Ketheric Thorm during  Find Ketheric Thorm's Relic. The party receive a mission from Disciple Z'rell after helping Balthazar capture the Nightsong. Z'rell congratulates the party for completing the mission but explains that there's one more task before she can grant an audience with Ketheric Thorm. Thorm seeks the safe return of his daughter, Isobel, and has sent a spy, Marcus, to the Last Light Inn to acquire her. Z'rell orders the party to aid the spy in capturing Isobel.

Meeting Isobel

After arriving at the Last Light Inn and gaining Jaheira's trust, the party can ask Jaheira how to get past the shadow curse as part of  Seek Protection from the Shadow Curse. Jaheira refers the party to the Isobel a cleric of Selûne, the woman responsible for the Last Light Inn's special protection. Isobel is upstairs on the balcony of the only separate room on this floor, reinforcing the Inn's barrier with the power of the moon.

Isobel instantly recognises the party as the True Souls with free will and provides them with a Blessing of Selûne. She explains that the blessing provides resistance to the lesser aspects of the curse, but is not enough to stave off the deepest parts of it. If the party betrayed Kar'niss during  Follow the Convoy and gave the Moonlantern to the Harpers, Isobel gives the lantern to the party. Otherwise, she simply mentions that the Harpers are working to learn how the cultists are surviving the shadow curse.

After wrapping up with Isobel, she hears something strange. Suddenly, a Flaming Fist named Marcus flies down to the balcony. Marcus telepathically reveals that he was sent to capture Isobel alive. The party can use a Wisdom check (DC 6) to probe further into his mind, revealing the task is of great importance to Thorm. The party can also tell him no, or say they'll help him. Isobel asks what's going on, and the party has an option to reveal Marcus' plan or state their intention to aid him.

Meeting Marcus early

Marcus vouches for the party.

If the tieflings were not saved during  Save the Refugees, either by raiding the Druid Grove or ignoring the quest, the events play out slightly differently. When Jaheira confronts the party at the Inn's entrance, Marcus comes forth to vouch for them. He uses his telepathic powers to tell the party to follow his lead, revealing himself to be a True Soul spy. After the confrontation, Marcus can be spoken to in Isobel's room upstairs, where he explains that he was sent on a mission to kidnap the cleric. The party can either attack him or agree to help him.

Battle at the inn

Marcus prepares for battle and summons his minions - six Winged Horrors. If the party sides with Marcus, then they face Isobel, Jaheira, Harper Bor, Harper Essius, Harper Naysa, Harper Mijah, Rolan (if alive), and Cerys (if alive). The party does not need to fight anyone beyond Isobel, where the goal is to knock her out with non-lethal attacks.

The fallen inn

Residents of the Inn fall to corruption.

If Isobel is captured or killed, the Inn falls. Everyone besides the party and Jaheira, who are protected by Selune's blessing, are either killed immediately or transformed by the shadow curse. The party faces a massive battle against the shadow cursed residents: Harper Karrow, Harper Terradissia, Harper Antony, Harper Chenti, Harper Lassandra, Harper Branthos, Harper Elindale, Harper Callie, Fist Ulthred, Harper Darragh, Harper Donner, Harper Elifer, Harper Skywin, Harper Teebs, Harper Essius, Harper Tumeril, Harper Meygan, Quartermaster Talli, Harper Hangfar, Harper Manus, Harper Lymn, and Dammon (if alive).

Additionally, Shadow Creepers pop up to join the undead, eventually joined by a Giant Shadow Creeper.

After the battle, if Jaheira survives, she states her intention to go to Baldur's Gate for more support. The party can either wish her luck on her journey, or suggest she join the party, to which she agrees.

The party can now return to Moonrise Towers and report to Z'rell. Depending on if Isobel was successfully kidnapped or died, Z'rell sends the party up to gain a reward or face judgement from the Absolute as part of the final segment of  Infiltrate Moonrise Towers.

Consequences

Losing the Inn has many far-reaching consequences. If the party did not speak to Counsellor Florrick on the ground floor, then she does not move on to Baldur's Gate and dies in the Inn. Art Cullagh also dies, preventing the completion of  Wake up Art Cullagh and  Lift the Shadow Curse. If Dammon has not been spoken to, Karlach's personal quest,  The Hellion's Heart can stall since he can no longer fix her engine.

Isobel is brainwashed by her father.

If Isobel is kidnapped, she appears at the end of Act Two during  Defeat Ketheric Thorm. Once the party reaches the bottom of the Mind Flayer Colony and is about to confront Thorm for the last time, Isobel is there as well. She has been infected by Mind Flayer Tadpole and enthralled with strange magic to keep her compliant. If the party aided Thorm in kidnapping her, she thanks them and says she was a fool to resist, then wishes them the best of luck in the City of Judgement. When the party fights Thorm, Isobel aids him. Even if the party manages to kill Thorm while leaving Isobel alive, she dies immediately after the battle.

Quest rewards

• Gift from the Absolute, if Isobel is successfully kidnapped.
