Wizards of the Coast is giving away free content over at dungeonsanddragons.com, and my D&D Adventurers League adventure DDEX1-07 Drums in the Marsh is available (via DMs Guild) for free until April 21. You can get it and a lot of other free material, some of which is direct download from the website, and others link to DMs Guild products. Get them while you can.
