“By the sound of it, she’s either sold her power, most likely via Cauldron, or she bought the power from them herself. In the latter case, it’d be odd that she suggested other buyers should ask for a refund and not she herself, so I’m leaning towards the former.” Remember the Merchant party with stolen powers in a bottle? It’s possible she stole it before it reached the intended buyer.
That’s a good point. It’s not the vibe I got from it, but this could very well be the case.
