From the introduction: AT MY SIGNAL, UNLEASH HELL! The united forces of the Five Nations march into the Mournland to wage war on the Lord of Blades. West of the Glass Plateau, they're met by an army the likes of which hasn't been seen since the heights of the Last War. Let battle commence! Optimized for APL 18, this is the second in a quartet of adventures, the Flames of War storyline. Welcome to the Oracle of War campaign, a new 20-part standalone story for the D&D Adventurers League! You can play this adventure as part of your own Eberron: Rising from the Last War campaign, or as part of the Oracle of War organized play campaign. While this campaign runs under the umbrella of the Adventurers League, it utilizes different rules. You can familiarize yourself with these unique campaign rules by checking out the Oracle of War Player's Guide and Oracle of War DM's Guide, found in the D&D Adventurers League Players Pack.
