Thank you for the detailed answer, mods! I like those ideas for possible consequences very much, and will work on incorporating bits and pieces of them into future threads with Daud. Rather than retroactively assume they've been going on since the beginning of the game, I think it makes more sense to play it as something that's started up again, so he can be appropriately on edge.

For shadow magic abilities: would it be possible to give Daud the ability to conjure the following?
- A shadow mask that allows him to obscure his face and offer some protection against attacks that may attempt to blind him or poison him (through any airborne substances).
- Humanoid shades (up to two at a time) that can serve as distractions, in the rough shape of whatever Daud is wearing/wielding at the time they're summoned. The shades themselves aren't very durable, but they are solid enough to have a limited interaction with their environment (such as opening a door/window, or briefly sparring with opponents, though they aren't strong enough to kill something) and produce realistic sounds of running/walking on surfaces.
