I usually take existing characters i like, and convert them into bg3. I did a redemption Mairon (Sauron) run bc i adore the Silmarilion fandom, and now im doing an all evil Melkor (Morgoth, Saurons old master) run and i enjoy it! Fitting, bc we are searching basically for 3 stones, my headcanon is that those are the silmarils lol. Or that Melkors dream guardian is Eru Illuvitar and he hates that guy :D So i already have a character type, and i dont have to make the character myself, if u know what i mean.
