The world of Sleyn is a little doomed planet made of blocks. Its World Core is under assault from a corrupting force known as the Ostrum, and it seems unstoppable. As a last-ditch effort, the World Core forcespawns a bunch of Dungeon Cores so they can level up and push back the Ostrum. So far, all have failed. This fic is a dungeon core set in the CoreVerse. You do not have to read any other CoreVerse book to enjoy this. It is heavily inspired by vanilla Minecraft and Terraria, with a healthy sprinkling of mod influence, too. PG-13 ish, with a sprinkling of profanity and some violence, but the descriptions are pretty tame.
