Happy one year anniversary, <NAME>! In Caracas, Venezuela there is a mysterious substance oozing from the roads known as La Mancha Negra. Since its first appearance in 1986, this strange ooze has caused numerous automobile accidents and claimed thousands of lives. All attempts to identify the composition of La Mancha Negra have failed. It grows when warm and wet, with the consistency of chewed bubble gum, and shrinks when cold and dry, becoming as slick as black ice. Almost as though it were a living thing. All attempts to clean it have met with failure. Detergents do not work. Nor do high powered sprayers. They went so far as to resurface the road, and La Mancha Negra returned. The application of crushed limestone merely made the roads undrivable for residents.
We have our own theories, of course. La Mancha Negra is merely to physical manifestation of a malignancy buried deep beneath the earth. A foul intelligence that stirs in its slumber and claims lives as sacrifice to slowly awaken. It oozes and grows, making itself manifest in the physical plane, while in the psychic realms it goes unchecked.
Indeed, we burrowed tunnels beneath the earth, leading to great caverns where we surmise the source of La Mancha Negra alights upon our world. Deep in a underground, something is beginning to move. We sent down locals to investigate, secured to lines with safety harnesses. There was a terrible, chiropteran screeching, followed by screams. Awful, bone chilling screams. The lines all went taught, then slack just as abruptly. When we pulled them back, all that was left were the tattered, blood stained harnesses, and scraps of cloth and hair.
Given your project management experience, we have decided to send you to the site to oversee operations. The first order of business will, of course, require you to tour the tunnels, so you might ascertain what happened to the missing workers. We trust you will not fail in this matter.
