All of the Baldurs Gate 3 companions have interesting backstories and great quotes, and Karlach is no exception. In fact, for a late addition to the game, Karlach is very well-developed. She has a very distinct personality and always brings a fun energy to any scene shes in. Shes also surprisingly upbeat for someone who is doomed to either die or return to D&Ds version of hell, making her hard not to love.
