Could make an intriguing encounter when searching for firewood..."Quite near there happened to be a mound of earth, at the highest part of which were growing thickets of cornel and a dense cluster of spiky myrtle-stems. I went up there and tried to wrench the green growth from the ground to provide a leafy covering for our altar. There I was confronted by a horrible and astounding miracle. For from the first bush which I tried to break off...blood oozed in dark drops, fouling the earth with its spots...A piteous moan came from the base of the mound and I heard a human voice answering me: 'Why, Aeneas, must you rend a poor sufferer? I am buried here...for I am Polydorus. Here death overpowered me in a crop of piercing iron-pointed spears. And so a crop resembling javelins has grown over me...'"
As you emerge from the shop in the alleyway, not-too-distant clanging and stamping makes you wary. Further investigation reveals a massive Balgrian protest march flooding the main street, banners roaring about the inhuman conditions in which this ethnic group is forced to live.
