The work a GM puts into a game can get rather daunting. There's tons of prep to do, and if you get behind, it can really mess things up. Thankfully, there's resources like Professor Humber Drumsley's Adventure Codex. It's a new book that's up on Kickstarter that's filled with mini-adventures for all levels, so a GM can just pluck one out and put it into their game as they see fit.
From the campaign:
You're in the middle of a major campaign. It's long and involved, and takes tons of prep. Now you're just hours away from your next session, and you don't have anything ready. Fear not! When Professor Humbert Drumsley shows up at the table, there's a problem that your players need to solve. Or Humbert is the problem, whatever works. At any rate, it will keep the characters busy for the night!
Professor Humbert Drumsley: 5e Adventure Codex is a collection of short adventures compatible with the latest edition of the world's oldest fantasy roleplaying system. Not only are these adventures ideal for low level characters, they're designed to be fun, fast-paced, and light-hearted.
Humbert is the stereotypical bumbling mage, perfect for introducing early in a campaign. He leans hard into the familiar fantasy tropes, and he brings along his special brand of kooky arcane accidents and unrelenting eldritch errors. You can use him to provide comic relief between major adventures, or to introduce your own quest hooks and plot points.
The finished Codex will be approximately 80+ pages in a 5.5 by 8.5 inch format. It will contain 10 short adventures, a character write up, statblocks, magic items, and more! The Codex is fully written and has seen a first round of editing. Illustrations have also been secured, using some top-notch artists from both in and outside the industry. Playtesting is ongoing, and we're looking forward to trying everything at the table before it's delivered to you.
The Kickstarter is around 3x funded (being fair, though, they weren't asking a lot) with still 31 days left to go.
