Barkaf and Balancing Point

Publisher's blurb:

In a world where adventurerers are fairly common, services specifically catering to them would exist. Enter: Balancing Point, a dungeon built by Modrons for the Orderly Conduct Company. It's an intentionally safe dungeon where kiddie adventurers can try finding secret doors, kill mobs, and fight a boss spellcaster. But not die, because that would be bad for business. Before a group of adventurers visit the dungeon, they have to go through the stinking small town of Barkaf which might be actually better than the dungeon.
