Meta: How would you describe your character's moral alignment?
[brief mention of sibling death]
For most of Talia's life, she was basically a perfect representation of Lawful Neutral. The rules and the code are an ends to themselves. The impact and intent don't matter. All that matters is following the code. She saw herself as little more than a pawn to be moved in order to achieve her pack's end goal, but she wasn't really a zealot for the pack's cause. She felt no personal investment in ridding the world of hunters, that's just what she did because it was what the pack wanted her to do
(While the argument could absolutely be made that her pack around her was Lawful Evil, Talia herself never really was. In her mind, her actions were all toward the end of balance. They sought to eliminate hunters, but only because hunters sought to eliminate them. Balance. If you wanted to argue that she was still Lawful Evil for operating within the bounds of such an organization, I wouldn't put up too much of a fight against you.)
Growing up, Talia valued fairness and honor to a higher degree than even her siblings around her. It's why she took the edict of control so seriously -- that's how she brought honor to her pack and her family. That was how she ensured there was balance in the world, by creating balance within herself. It's also why so many of the pack's practices made her a little sick. She didn't want to fight another pack member when they were already wounded on a new moon, even just in a training exercise. Being able to win, in that circumstance, didn't bring her any satisfaction because it was dishonorable.
Since leaving her pack, though, Talia has been taking a steady right-ward journey across the alignment chart. I think Talia herself would insist that she fell somewhere closer to Neutral Good, but that would be wishful thinking on her part, or aspirational perhaps. Either way, she's firmly in the Chaotic Neutral camp.
While she doesn't value chaos, as some reading of this alignment propose, she does value full freedom from dogma and just about everything else. A fun shifting of her lever has occured: where before she was a slave to order of her pack but not so much the ideology of the mission, she has now completely thrown off the constraints of that hierarchy while throwing herself into the mission.
But Chayya, you ask, wouldn't that make her Chaotic Evil? Maybe in mindset, but not in action. Despite what she thinks and tells others about killing hunters, she hasn't actually devoted herself to the slaughter of all hunters (and won't). She wants to, because that's the means she's chosen for avenging her sister's death. And sure, she absolutely has killed her fair share of hunters. But since settling in Wicked's Rest, her devotion has actually been entirely to....whatever the fuck she wants to do. For the first time, she has the freedom to make her own choices. That was paralyzing but only for a short while, when she was moving cross-country (and there was maybe a brief period then when she did fit into a more Neutral Evil or True Neutral alignment), but she has settled wholly into the ability to do what she wants, when she wants, and for whatever reason.
What about how much she cares for others and wants to help them out? Yeah, but only her people. She's not going out of her way to offer a hand to just anyone -- we've seen this in her ample complaints about tourists and others that she has to give a hand because of her job. And, while all people can burn out, Talia's recent lapse into apathy, near antipathy, toward those she has to help I think further solidifies her Neutral stance. Sometimes she behaves in a way that's Chaotic Good, sometimes Chaotic Evil, but overall what she's doing is behaving the way she wants to in that exact given moment, which to me feeds into Chaotic Neutral.
Additionally, her own view of good and evil falls to more neutral territory -- just ask her and she'll tell you that she's a "realist," believing good to be naive and evil to be radical, and both of them to be boring.
