Copying myself from Reddit:

First run: Dusk, a Seldarine drow druid. She grew up in the Underdark, learning about the flora and fauna there initially for the purpose of making poisons and such. Every once in awhile, something would make its way down to her from the sunlit realms - a flower, a critter, etc. - and she grew... curious. Then more than curious. And finally, one day, she took an opportunity to escape, and explore the strange new world for herself.

Next run: Merrilee, an elven or half elven bard (wood elf variety) with lots of frizzy red hair. A bit mischievous, a bit naive, she makes her living as an entertainer at one of the smaller taverns in Baldur's Gate, doing some acting on the side. She's the daughter of Gorion's Ward and Xan. I'm gonna do my best to recreate my favorite BG1/2 portrait in the BG3 character creator.
