Just because I am bored, here are my various characters that I have played, am currently playing or plan to play:
Siova Tav
My first character, she was made pretty much just because I found it very funny to have a devil-looking character get powers from a god, so I chose the most good-oriented-sounding god from the cleric list... and somehow I ended up falling in love with her.
She grew up in the Open Hand Temple after her father was murdered and her mother left her there and never came back. I imagined her to be a lot like Tohru Honda from the "Fruits Basket" manga/anime, where she is not book-smart but has a lot of wisdom and kindness that makes people like her and feel safe around her. She has her long hair in a braid because her mother's family used to do that as part of a tradition, she dislikes having the hair free. Her eyes are also naturally darker, but got a glow after Ilmater accepted her as his cleric. She loves meeting people belonging to different gods and to learn from their point of view the world, but over time she is not afraid to stand by her own views of the world, life and divinity, which lead to quite a few arguments between her and especially Wyll, Gale and Astarion.
She romanced Wyll and followed him to Avernus to take down Mizora, although she does not want to adventure forever. Because I want the best for her, in my head she convinced/Command'ed the two opposing Prism-prisoners to cooperate, and used her Divine Intervention to save Karlach since I never had to use it in the story.
She is my main Tav, the other characters are there more for fun to make slightly different choices.
The Sad Surge
This is the Dark Urge of Siova's story. Technically she does not have a name, but because all my characters accidentally ended up having "S" first in their names, I call her Surge. She has selective eidetic memory with anything to do with death and blood (for example she can easily recall murdering Siova's father in all its gory details from a random urge to kill, but otherwise her memory is very blurry).
Surge and Siova never meet; while Siova was busy with helping people around her, Surge ran past it all in order to get to Baldur's Gate and take back her birthright. She was killed by Orin, and Siova found her corpse after defeating Orin.
I am making an "alternative" story for her where she does follow the regular Dark Urge-playthrough with companions and such, but still waiting to see where that goes. Apparently elves have a child name until they are considered adults in their 100's, so the idea then would be that she would finally make a true name for herself, if she went with a redemption story.
Sharin
The bard, a lover of colour, fun and freedom, Sharin is willing to help others around her, and takes everything with a laugh most of the time. Seems to be unbothered by almost anything with the exception of other people claiming her in any shape of form; she romances Astarion but him flirting by saying "tonight you're all mine and I'm all yours" was a big turn-off even if she knew what he meant. As such, she hates Raphael and uses every opportunity to make fun of him and insult him, because she was very provoked by the idea of selling her soul to him. Unlike Siova Tav who happily shares her past if asked, Sharin hardly ever alludes to it even if there are hints that there are more to her than it seems; she is a drow who has lived on the surface for a long time, she carries a lot of Lolth-sworn knowledge but has the look of a Seldarine, and sometimes has the bearings of a noble as well as an entertainer. She often jokes that she might embark on her own journey of growth when the Absolute is taken care of alongside Astarion.
Sharin angered the Emperor and was forced to take Raphael's offer, putting her soul on the line to save the world. Knowing this and her hatred of being owned, she asked to be made an illithid, and had Gale gather the Crown of Karsus before having Orpheus complete her transformation and killing her; the idea was that ceremorphosis destroys the mortal soul, meaning there would be no soul for Raphael to claim when she failed to give him the Crown. Thus she would save the world, free an old prisoner and give the finger to Raphael one last time (she never went to House of Hope, she had no idea it was there).
That is, that WAS the plan, but then Patch 5 arrived and Withers revealed that for some reason she still had her soul after the ceremorphosis, and she was met by a very angry Raphael.
Sissi
Sissi is a Paladin with the Oath of Vengeance. Having grown up as an urchin, then taken in by some noble people far away from Baldur's Gate that since were killed by and with their killeds in an explosive robbery, Sissi vowed to help give vengeance for those that deserved it. She is a "do unto others" and "ride and die by her friends" kind of gal; if someone is kind of her, she will be kind back, but if she has a reason to begrudge, she will carry that forever; only reason Wyll survived trying to attack Karlach was because Karlach vouched for him and Sissi would easier keep an eye on him, otherwise she would have killed him.
With her, I made her mostly for fun because I wanted an all-girl group (with the exception of Wyll because I am weak and Halsin because Sissi romances him; they are never allowed to be used), who were all tanks. Karlach and Lae'zel stay as their classes, same with Jaheira except she is constantly in owlbear mode if I need her, and Shadowheart was respecced to War Domain Cleric. She was also made a half-orc more because I wanted the colour differences. I am still playing Sissi, but with her I am actually thinking about having her attack Gortash first chance we get, just to see what happens and if I will be able to defeat him, the guards and the Steel Watchers, because again, ride or die, and Karlach wants him dead? That's reason enough to blast the ceremony. Also at first I thought to have her romanze Lae'zel or Karlack, but I read somewhere that half-orcs have a shorter lifespan, so I found it funny if she was only 30 but mentally 45 or the like, or at least that she was mentally the same place as Halsin, even though she does not have the same life experience, and so they ended up together.
Su'zan
This is Su'zan, who's bakground I am still not quite sure about since I have just started her. She is the Sorcerer of my characters, specifically a Wild Magic sorcerer; her hair, scar and eyes are results of Wild Magic Surges. She is going to romance Karlach, who will be a Wild Magic Barbarian. More than that I am not sure, I look forward to learning more about githyanki through her!
