Among the many character arcs in Baldur’s Gate 3, Karlach’s journey stands out as one of the most emotionally gripping. A fierce yet warm-hearted tiefling barbarian with a hellish engine burning inside her, Karlach quickly becomes a fan favorite thanks to her personality, tragic backstory, and unbreakable spirit. Her narrative is tied deeply to Avernus, the first layer of the Nine Hells, where she was once enslaved. Throughout the game, players become invested in her quest to live freely and escape the cruel fate of returning to that infernal plane. However, many wonder if it’s possible to prevent Karlach from returning to Avernus entirely. This topic explores what is currently known about this outcome, including player choices, narrative consequences, and possible future updates.
Understanding Karlach’s Infernal Engine

While it grants her immense power, it also burns hotter the longer she stays in the Material Plane, making her presence there unsustainable without intervention. This burning dilemma shapes her story and gives players a moral and emotional investment in her future.
Key Points About Her Condition
- The engine cannot cool down on its own and will eventually kill her if left unchecked.
- Returning to Avernus prevents the engine from overheating, but at the cost of her freedom.
