In Baldur's Gate 3, Mol is a young Tiefling who first appears in Act 1 at the Emerald Grove Tiefling Hideout. If you save her people, she moves out of the Grove and can be found in Act 2 at the Last Light Inn in the Shadow-Cursed Lands, where she acts as a vendor until she is kidnapped during an ambush

. However, the quest "Find Mol" in Act 2 involves searching for her after this kidnapping. Despite clues suggesting she might be in the Mind Flayer Colony or Moonrise Towers, Mol is actually not found in these locations during Act 2. Instead, you must progress to Act 3 to find her

. In Act 3, Mol can be found in the Lower City of Baldur's Gate inside the Guildhall, which is the secret underground headquarters of the city's thieves. The Guildhall can be accessed through several routes, including:

• Entering the sewers via a manhole near the Glitter Gala and clearing noxious fumes to reach a door into the Guildhall.
• Going through the Basilisk Gate Barracks' prison entrance and falling through a pit latrine to access the sewers and then the Guildhall.
• Assisting the Guild near the beach west of the South Span Checkpoint and gaining permission from an Orc to enter the Guildhall front door

Mol's exact coordinates in the Guildhall are approximately X:-11 Y:751. After finding her, you can interact with her and progress the quest. Additionally, Mol's contract can be found in the House of Hope, which involves some hidden areas and checks, but this is part of a later storyline

. In summary:

• Act 1: Mol at Emerald Grove.
• Act 2: Mol at Last Light Inn until kidnapped.
• Act 3: Find Mol in the Guildhall in Baldur's Gate Lower City.

This means you cannot fully complete the "Find Mol" quest in Act 2 alone; you must reach Act 3 to locate her in the Guildhall
