Mists of Akuma: The Yai Sovereign of Storms

A 5th Edition OGL adventure for four to five PCs of 7th-8th level set in the Mists of Akuma campaign setting.

Soburin’s human nobility are not the only rulers that are in need of outside agents since the corrupting fogs reappeared; even oni warlords have found the Mists of Akuma to bring challenges, obstacles, and threats beyond their ken. Yōna, the undisputed master of the secret city of Tsukisasu, lost control of her throne only a few weeks ago to a strange creature that capered out of a storm intermingled with the supernatural haze, and her agent Xiqzoxix is keen to remove the usurper as soon as possible. The PCs are the group ze has chosen for this momentous task and should they accept the oni bengoshi’s offer, a deadly set of trials await them on top of the mountain—though the longer they dally, the more powerful their adversary grows. To defeat Obiemashita the party will have to first find Tsukisasu, covertly investigate the town, and then disrupt the yai sovereign of storm’s rituals and slay it before all hell breaks loose, spilling untold violence down onto the already embattled lands of the prefectures below!

Will you conquer Tsukisasu or be subsumed by the storm?
