From the publishers blurb:
STEP BOLDLY INTO THE MOURNLAND!
The brokers of Salvation pay good coin for artifacts scavenged from the haunted battlefields of the Mournland. In this nest of cutthroats, daring explorers gather to carve their destinies from the ruins of Cyre. The adventurers head deep into the Mournland to rescue a missing salvage team. In the heat of battle, they unearth a strange device from the ruins: the Oracle of War. This machine knows all the secrets they need to overcome their enemies—if only the adventurers can figure out how to operate it! This Tier 1 adventure is optimized for APL 2, and is the second adventure in the four-part Spoils 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.
