You also find out in Moonrise Towers that the drow who supposedly abandoned Lloth did not in fact abandon her. Ketheric with his advisor trapped drow by tadpoling drow scouts, sending them to whisper of the Absolute in the Underdark, and the angry Matrons would send Lloth loyal hunting parties after them. Ketheric reasoned it was worth it to sacrifice one tadpoled drow to ambus the entire hunting party and convert them via tadpole, as drow made natural leaders to the chaff in the army. You can find this in the books/letters around Zrell, Balthazar, and Ketheric's chambers in Moonrise, alongside with missives mentioning their alliance and plans with Gortash and Orin.
Minthara in essence is a drow that was captured in a hunting party like all drow in the Moonrise Towers, and their memories were manipulated by the tadpole.
Minthara also says as much if you have her in your party. If you ask her how she was captured, she will tell you
she killed some cultists for encroaching on her turf in Menzoberranzan, then led a small party of assassins to find out where they were coming from, then was personally greeted and captured by Ketheric Thorm and Orin the Red.
Nice to know it lines up, I never found those notes!
To the thread title, the Seldarine/Lolth-Sworn distinction seems to be a somewhat strained way to allow the player to indicate whether they are playing "good" drow or "evil" drow to the game. Although it doesn't limit your roleplay options in any way.
