The creature and prop artwork in our published modules is commissioned from named human artists. That is a promise we have already made, and it does not change.
We do use AI tools elsewhere in the studio. Concept exploration, art direction, layout roughs, and the procedural assembly of our virtual tabletop map packs all involve them. Every one of those passes through a human hand before it reaches you: a person decides what is being made, a person judges whether it is good enough, and a person finishes it.
Our house style took years of tuning to arrive at. Nobody else has it, because nobody else built it. That work is ours whichever tools were held while doing it.
We would rather tell you exactly where the line sits than claim a purity almost nobody in this industry actually practises.
