At the south end of the battlefield is an eerie formation of enormous boulders, balanced in precarious ways, riven with crevices, and surrounded by dark forests and towering hills. This place is named the Devil's Den. If you seek to find a spirit at Gettysburg, here you will find one. But it is one you will not wish to find. The spirit is pure evil, and came into existence a millennium ago, sprouting from a seed nourished by human blood. It lay dormant, until reawakened by the blood spilled so profusely at Gettysburg. That Spirit was hostile to those who passed within its realm, and punished them in mysterious and inexplicable ways.

On November 19, 1863, when President Lincoln gave his famous speech, he said that "we cannot hallow this ground". "Hallow" means "to make something holy or sacred". Most people, when in a holy or sacred place, show appreciation, and behave in an appropriate manner. But for some people, there is no appreciation. For some people, this is a place to exploit for money or personal benefit. For some, it is a place to cause rampant and mindless destruction, to shock people by mocking acts of vandalism. For others, it is a place that they have no desire to visit or understand, a place to be endured, and they disdain those who feel appreciation or respect. The Spirit did not discriminate among its victims. All are fair game for its evil.
