Sinpools are deep pits in which the sins of the living well up and overflow in a thick fluid, similar to black oil or tar. Not much is known about these pools, as they have only been witnessed by a handful of unfortunate souls and are far too dangerous to study up close.
An extremely rare phenomenon, these pools only manifest in places where unspeakable atrocities have occurred, where dark magic has saturated the air and death has dwelled too long. They are portals; piercing a hole between the planes of the living and dead, ripped open by the hands of war and suffering, loss and sorrow, betrayal and corruption. The essence that seeps out is demonic, but not yet a demon. It has a will, but not a mind, a longing to live. It is the embryo of a demon, the raw energy that makes them what they are.
Sinpools can take hundreds of years to fully develop. They bubble up from the ground slowly, goring their way up from below before breaking through the surface. They may shrink over time if left undisturbed, or they may grow wider and wider, swallowing up the area around them, should the darkness of the land become too great, where no light can shine through any longer.
