Not a racially segregated hospital, but rather the Private Medical Complex
The G&M, or GaMa Corp, not to be confused with the larger GM corporation.
It is taken for granted that medical technologies will advance apace in the future, permitting rapid healing and perhaps even shaping of the human body. This submission is to provide possible flavors for that medicine to come in.
At that moment the drizzle eased, and Ledoik could see as plain as day a blight upon the fields near the edge of the forest. Like a rock dropped into a pond, a wave of lighter shades of green emanated from the blights centre. Growing from the forest, where it was darkest, the field got lighter and lighter the further away it was from the blight. It was clear enough. The commander barked words, organising the archers, the few catapults they had and the giant rockslings to this side of the battlements. He motioned them to aim towards the blight, the dark patch near the fields edge
Blood, biles black and yellow and phlegm, these are the four vital humours that govern our bodies. Understand them, and health is a simple matter.

A palimpsest is a manuscript, usually of papyrus or parchment, on which more than one text has been written with the earlier writing incompletely erased and still visible.
After the PCs defeat (or force the rapid retreat of) a villanous necromancer/demon summoner, they discover a book. This book outlines how to summon a demon whose power increases according to the size of the summoning circle used to summon it. And after the PCs examine a map of the country, they find that the layout of the cities and roads match up with the required summoning circle. In fact, the final road that would complete the circle is currently in construction.
With anyone who can find out about the circle and the ritual to summon the demon able to somehow make the final road/line, and destruction of the cities and roads currently in existence out of the question (unless this is an evil campaign- that removes the moral quandary), how are the PCs going to solve this problem?
