Blue crystal

I played for 5 months, and with some effort, I managed to fend off the enemies (although without antimagic – by the way, it's not even in the tome of light magic) and finally reached the prophet. I found everything he asked for, and then some strange thing happens. He takes the boots and the rune, but for some reason, he doesn't want the dust and doesn't take the resources. When I try again, he asks me not to bother him. What's going on? Is this a bug? I tried to go to the treasure room, but it's already empty. It's a tricky situation; what should I do?

And also, it's impossible to understand anything from the attached description of the map walkthrough because the text is not visible (is it some kind of cipher?).
