Mercy, Nevada

Mercy was a town in Nevada.

History
In 1870, the town was in danger of starvation after the arrival of Kahler-Jex, who was being hunted by his cyborg Kahler-Tek for his crimes as a war criminal. Around its border, a line of rocks was placed so that no one could escape or enter. (DW:  A Town Called Mercy)

Behind the scenes
Although the script never specifies that the town is in Nevada, set decoration heavily suggests that this is the case. In Isaac's office, for instance, prominently features a reward poster issued by the office of the Governor of Nevada.
