@arcandoria should never have made these thingsies, because I'm obsessed with them now and I physically can not stop making them.
Anyway, this here is Salira, my supposed to be evil run Tav. In the end, she isn't fully "evil" and more my...insane run? I use a d20 every time I have to make any choice in game and have to go through with it - so bye bye last light, hello slayer form I guess!
Characterwise, Salira is a wrong'un. There's not much else to say. She's deeply vile down to the core and she'll happily show her rotten heart to you if you ask. Once she's on a spree, there's no stopping her and she'll happily present a pile of corpses to daddy Bhaal.
She wasn't always like that. There's a reason for why she is the way she is, but it's extremely graphic and cruel so I'll just say: Her past was bad. Things happened and she slowly but surely became twisted and insane.
Astarion and her newfound friends - as well as the Orin and Worm induced amnesia - make her want to try and get back onto the good side of life. It's a little hit or miss - more miss, tbh - but she tries.
She tries, eventhough it will eventually be for nought.
At this point - try as hard as she will - there is no turning back. Bhaal is well aware that his child has already lost the battle before it ever begun.
And, deep down, Salira knows it too.
