"I went into a player's house and saw this creepy altar with a book open. I clicked on the book and read it to the end. It was clearly written by the player and was kinda meh, but most interesting was the option to load instance on the last page. It loaded this huge instance that was created by the player with objectives just the same as you read about. A terrifying boss at the end would only take damage under the spell of a specific melody. Without a bard, any group would fail."
