Overall plots aren’t what grab me (and most readers imo). What do are the thematic takeaways, great characters, immersive world building, pacing, and the art/prose. I don’t think your summary has enough of those things for me to gauge my interest.
Things im curious to know: What does the stone represent? What are the MC and witch like? What internal/external challenges do they face? Why are revenge, domination, and regaining memory important motivations to them? What sets your world apart from other fantasies? Etc
