Plot

The events of Pathologic take place over the course of twelve days in the remote Town-on-Gorkhon on the Steppe. When an outbreak of a unique strain of Plague grips the town, three healers—a Bachelor of medicine, a Haruspex surgeon, and a blessed Changeling—must race to discover the cause of the Plague and destroy it.

The Bachelor's Path
The Bachelor, persecuted by the Powers That Be and desperately seeking a way to bring legitimacy to his imperiled lab Thanatica, is invited to the Town by Isidor Burakh. Isidor believed that Bachelor's quest to discover how to prevent natural death would benefit greatly from a meeting with Simon Kain, a reportedly immortal man. Upon arriving, Bachelor is invited by Eva Yan to lodge at the Stillwater.

The Haruspex's Path
Haruspex returns to the Town after receiving a letter from his father, Isidor Burakh, who fears that his death is imminent. Haruspex intends to see his father before his passing, and to receive his inheritance: a place of authority in the Order. However, arriving at the Train Station, Haruspex is descended upon by a vicious mob that believes him to be a recent serial killer. Haruspex manages to cut down several people, but must flee before he is overcome. Injured, Haruspex vaults a fence and stumbles into a seemingly-innocuous warehouse.

The Changeling's Path
Changeling awakens in a freshly-dug grave, uncertain of where or why she is. She is beset by visions of a mirror image of herself—a twin?
