The Shadows watch, silently, as you take your ax to the mound. Scraping off the lichen iand moss is easy and doing so reveals a large pile of... something.
There are pieces of cloth, wood, and leather all piled in layers. Curious, now, you keep going adn, As you get deeper into the mound, the leather gets crustier and the cloth more and more rotted. Interspersed in all this are occasional copper coins. Feeling almost compelled by the need to know, you go even deeper and, nearest the bottom (as far as you can tell), you find what at first look to be a dozen or more grey-brown oblong orbs.
Until you manage to turn one a bit and realize that what you're looking at are skulls.
A dozen or more and, judging by the other detritus around them, old. More than days, months or even a year.
The Shadow nearest to looks at you with its black-pit eyes briefly, then goes back to join the others.
