Dungeon Blade.

What happens when a sword enchanted to test the worthiness of its wielder accidentally becomes imbued with a soul and made into a dungeon core, created and designed to test and challenge the adventurers of the mortal races? Not even the gods know, though they are interested in finding out. With a previously retired dungeon fairy on his side, Karrig, the Dungeon Blade, will have to contend not only with adventurers who have their own politics but also with the churches, who are very interested in the fact that one of their artefacts has gone missing and very much want it back. First time writing so that any advice would be appreciated. Apologies for the rough summary. I'm not sure where this story is going. Using Grammarly to keep it from being a grammatical nightmare.
