What are some hard decisions that she's faced since leaving Morrowind? What are three moral pegs that she clings to no matter what?
The biggest decision Ilyvi had to come to terms with was what was she supposed to do next. Her entire life seemed to have already been written for her with prophecies and the dictations of otherworldly entities, at least up until she fulfilled everything her “destiny” foretold. Everyone had expectations of her as the Nerevarine, but she never had any expectations for herself other than to live. She had no true skills outside of being a blade-for-hire, no interest in doing politics or continuing to being a nation’s “hero”. But there was very little she could do, yet with the rising tensions with the fall of the Tribunal, she had to come with some idea and a fast one.
Skyrim was desolate enough that no one would come looking for her, close enough to Morrowind where her presence would be overlooked for the most part, and she had so much money and stuff that, in such sudden clarity, she didn’t need to do anything.
The second hardest decision have been where to live. The north-eastern section was too cold, Riften was too packed for her liking, and none of the other Holds held much interest. Falkreath was, perhaps, second in the running outside the marshes of Hjaalmarch, but its proximity to the border put her off. She wanted to go deep into the country, to disappear entirely, and the marshlands of Hjaalmarch was perfect.
As for her morality, three things stand out:
Kill fast. Death is a part of her, part of her soul. From assassin to werewolf to hunter, Ilyvi firmly believes in killing swiftly. To prolong the pain and suffering is needless and unnecessarily cruel, so her deaths are planned with teeth straight to the throat or blade to the heart.
Steal only what’s necessary. Ilyvi does not like theft. She’s a master of stealth, her feet and paws silent, but from the first tomb she raided for a mage just to get some information, it always left a bad taste in her mouth. Since then she’s only stolen things she needs- food, keys, documents- and only if there was no other way to obtain it.
Remain skeptical. Always. She’s seen enough people following others blindly without questioning the facts, ordered around by gods and daedra with no clear explanation as to why it needed to be done. Ilyvi has no trust in those beings who think themselves superior, will stand firm and refuse if things are demanded at her. She is no one’s slave or servant, and she’s had her chain yanked one too many times to go back to not questioning authority. Always get the full picture, always demand answers for your questions. If they refuse or deflect when their answers matter, they are not to be trusted.
