Capture Isobel the Selunite Cleric Walkthrough in BG3

This quest begins upon returning the Nightsong to Ketheric Thorm at Moonrise Towers during the Find Ketheric Thorm's Relic storyline. After assisting Balthazar in capturing the Nightsong, Disciple Z'rell gives the party one final mission before meeting Thorm: assist a spy, Marcus, in retrieving Thorm’s daughter, Isobel, from the Last Light Inn.

Reaching Isobel

At the Inn, after earning Jaheira’s trust, players can learn about protection from the shadow curse. Jaheira points them to Isobel, a Selûne cleric responsible for maintaining the Inn's magical shield. She offers a blessing that provides partial resistance to the curse.

If the party gave the Moonlantern to the Harpers during Follow the Convoy, Isobel hands it back. Otherwise, she shares that the Harpers are investigating how the cult survives the curse.

The Ambush

As the conversation ends, Marcus, a disguised Flaming Fist, descends onto the balcony. He reveals his mission—to capture Isobel alive. Players can delve into his mind (DC 6 Wisdom check) or choose to support or oppose him. Isobel becomes suspicious, prompting a choice: expose Marcus or side with him. 

Alternate Encounter with Marcus

If the tieflings weren’t saved during Save the Refugees, Marcus defends the party when Jaheira challenges them at the Inn entrance. He secretly reveals himself as a True Soul and explains his mission upstairs. Players may cooperate or confront him.

Fight at the Inn

If Marcus initiates combat, he summons six Winged Horrors. Siding with him pits the party against Isobel, Jaheira, and any surviving Harpers. The goal is to subdue Isobel non-lethally.

If Isobel falls or is taken, the Inn collapses. Most residents are either killed or transformed by the curse, triggering a large battle. Jaheira survives due to Selûne's protection and offers to travel to Baldur’s Gate or join the party.

Aftermath and Consequences

Returning to Moonrise Towers, Z’rell either rewards the party or subjects them to judgment based on the outcome.

The fall of the Inn has major consequences:

• Florrick dies if not spoken to beforehand.
• Art Cullagh dies, though Wake up Art Cullagh can still progress via Speak with Dead.
• Karlach’s quest stalls if Dammon wasn’t contacted earlier.

Isobel’s Fate

If kidnapped, Isobel reappears at the climax of Defeat Ketheric Thorm, now brainwashed by Thorm’s magic and a Mind Flayer tadpole. She supports Thorm in battle. If spared, she still dies after the fight concludes.
