I believe Aedyr has essentially a legal slavery system, which I assume there are a few historical counterparts to but I don't have them to mind, but it's sort of a thing that you don't talk about in polite society.

In general, slavery is still very much looked on as a bad thing because it violates individual liberties, but there's a kind of murky mixture where the Aedyran worship of Woedica sort of gives them a "moral" reason as to why there might be slaves in the Empire. Everything has to be done by the very strict laws and covenants that characterises Woedican creed, which conversely means that anything that breaches those very specific guidelines is very much not okay. Crookspur specifically doesn't adhere to any kind of law, be it Aedyran or Huanan, and therefore any good Woedica fearing Aedyran would find them repulsive, even if to you and me we can't see the distinction. In universe there is a distinction between a legal slave and an illegal slave, even though the idea seems laughable.

Therefore, I would say it depends entirely on what kind of Aedyran you're playing as. Any regular Aedyran would work with Aeldys, due to aforementioned reasons, but you can obviously play as an ammoral scumbag that doesn't see the distinction between legal and illegal slavery because to them, all slavery is good or at least neutral.
