Given that I live in the city of Boston, itself not the worst place to spend a college lifestyle, I have noted that it is distinctly difficult to see the stars in the sky due to light pollution.
Here would be a chart what has blighted in the natural world.
D10 Blighted Lands
1- A vast swamp, approximately ten acres around and bordered by several sets of rusted and broken metal fencing. In direct sunlight it boils and bubbles with decayed muck, and at night small mammals who thrive in desolation swarm to strip the surface of anything edible. Any trees in the area have been reduced to gnarled sticks covered in blooming fungus, which has spread slightly to the surrounding environment not regularly treated with fire.
Roughly in the center of this is a tall, oblong metal device, warped from heat and leaking a thin, poisonous fluid. Inside can be seen clogged vents and burnt-out sensors. (Save v. Poison)
2- The western boroughs of the city of Just, cut off from the rest of the populace by vast, hastily-erected walls of clay and appropriated brick from the closest brownstones. Former streets are now shallow, slow streams of human refuse and excess rainwater that flow outwards towards the local lakebed and breed as many diseases as can be counted on both hands. Adventurously stupid street children claim to be able to see the bones of those victims of that plague that cut in half the population, and street beggars seeking to avoid rancorous Bluecaps press dried salts to their noses and sleep where the mortar has crumbled.
3- Beneath the filthy, smoggy clouds borne by residual hydrocarbons and sulfur dioxide, reside an approximate twenty thousand humans—survivors of what could be technically called a war—in a vast camp of canvas tents, metal sheeting, and small trenches. Those that have the sense to speak cannot communicate well, and most have lost the skills to do anything beyond eat, work and sleep with blank looks to the sky. In the distance, vast, screaming explosions can be heard tearing up the planetary crust and evaporating the oceans.
4- The collapsed crown of a mountain range, having fallen upon itself due to the honeycombed series of ancestral tunnels within compromising its stability. Between the boulders and settling dust, small glimmers of intricate masonry and jewelry can be found if one digs around enough. At night one can hear groaning from underfoot.
5- At a distance, it appears to be a monolithic structure of rough grey stone and steel crossbeams interspersed with corroded signs in a language you can't read. Closer up you can observe the vast faults and patches applied with metal and cement, the graffiti tags and the carvings by impulsive youth and bitter guardsmen who's families were sentenced to patrol its territories while the rest of the world moved on to build supposedly improved models of the machine inside. This is the fifth monolith in the area, and inside is still sickly warm from the gradual decay of unstable elements.
6- A very concentrated area—namely, that of the basement next door. However, the deeper one goes down those catwalks and ladders, the less solid the walls feel, and the thicker the dust hangs in the air. With this instability comes with a certainty of mind that one can most certainly reach the base floor. (Save v. Charm)
The deepest anyone has come back from is thirty-three floors.
7- The parking lot five blocks over, at the edge of town, where the homeless sometimes gather in deepest winter and seem to be less interested in other people than usual. Summer it is always abandoned, and if you stand upon it for a few minutes you will notice the most subtle of rising-and-falling motions beneath your shoes before the heat begins to scald your ankles.
8- Upon the death of the warlock Cantileve Soisan, their tower became a writhing tower of gnarled corruption as vast sky-wyrms spawned and regurgitated to fill the sky. For a week clouds were drawn into the vast gullets of these sky-wyrms, and for a week sunlight beamed upon their backs as the people below fled in all directions to avoid the encroaching night. The rain has grown hot and sulphurous—tears of the wyrms—that burns out anything that touches it.
9- The departure of the Great Pyramidals was marked with a great deal of sorrow and a great deal of loss; mostly in part due to the draining of the planet's oceans to aid in cooling vast subspace-rip engines. Having been polluted and genetically-modified tremendously in the prior centuries, inhabitants of these oceans did not take very well to an effective death-sentence and dealt equal blows to remainder engineer humans.
10- As you slept away your infection, every other time you awoke the hospital ward was dark and smelled of sterile cleanliness. You dare not leave your bed, for the feel of icy liquid is ankle-deep upon the floor.
