Very nice character story there. I love finding out how others build their Dark Uge, because in my mind, it is the only playable character that really connects with the previous games.
My Dark Urge is a Drow Ranger. (A trope, I know, but I wasn't thinking at all about... that guy.) She was previously a Gloomstalker, a sniper from the shadows, back when she was working for her daddy. I figured Bhaal didn't want to make another human since that didn't work out so well before. He wanted someone who could terrify just from racial and cultural reputation.
(In the previous games, I ended up playing through as a Cleric of Lathander when BG1 first released. So this time, I'm playing a Ranger/Cleric. Obviously I don't play evil characters.)
So Eilistraee came to my Dark Urge while she was unconscious in the pod, and when she woke up, this is the only thing she could remember, besides how to shoot a bow. (And yes, I know that Eilistraee is not fond of bows, but the Dark Urge was an opportune project for her.)
I started off as a Beast Master because doggo, but when I realized how godawful the pet pathing is, I found the Drakewarden mod so the pet could fly. My only complaint with that mod is that I have to use a white drake instead of a silver one which is the beloved of Eilistraee.
