Jens' Reign of Winter
The Black Rider
The Black Rider, or Black Midnight, is one of Baba Yaga’s Riders, the heralds who proceed the Witch Queen to Irrisen so they they may judge the inhabitants of that snowy realm. The Black Rider performs his duty only under the cover of night, leaving the daylight hours to his companions, the Red and the White Rider. Baba Yaga refers to this rider, whose mount is fierce and black, as ‘My Dark Midnight’.
With his dying breath he entrusted the pcs with finding Baba Yaga and saving Golarion from eternal winter.
