Karlach's infernal engine was a late addition to her character in Baldur's Gate 3: 'One of the last things that fell into place was the heart'

Karlach is one of Baldur's Gate 3's most beloved characters—and for plenty of good reasons. She's big, has potent golden retriever energy, and can probably bench press me—but she's also, like a lot of the game's cast, spectacularly well-written. Her journey of betrayal and punk-rock redemption is compelling and moving, to the point where the lack of a «perfect» ending was a point of controversy.

Broadly-speaking, I'm not on that particular conspiracy train—while I think from a critical standpoint the game's ending at launch felt a touch thin, that was later solved with a massive epilogue patch.

Regardless, Karlach's missing heart felt like such a central pillar of the character that I was shocked to learn, while attending BAFTA's «An Evening with Baldur’s Gate 3», that it was actually a somewhat late edition to everyone's favourite big tiefling wife.

During an interview (hosted by Jane Douglas) with Larian CEO and co-founder Swen Vincke, writing director Adam Smith, and lead writer Chrystal Ding, it was revealed that Karlach didn't get her infernal engine until much later in the creation process.

In fact, Karlach had the most changes overall, says Smith: «We had a lot of different concepts, and one of the last things that fell into place was the heart. We didn't have the heart for a long time—this person was [just] a fugitive from hell.»

If you're familiar with Karlach's early access self, you'll likely be familiar with this engine-less tiefling. The party was iterated on plenty during the game's EA period—Wyll, for example, had an extensive rewrite somewhere along the river of development. Still, I'd always imagined that Larian had simply moved the reveal of Karlach's heart to Act 1 along with the character's visual redesign—since it's pretty hard to play coy about having a luminous ribcage.

«At some point we were looking for the extra coolness,» Smith adds, though the team also wanted to answer the question of "'What is this character's thing about them that we
