Doomed by the Shadow…
The Swollen Shadow’s magic is such, that anyone transported to its demi-plane, will always first arrive in the somber and hazy Umbral Fens, which surround the City of Shadow. After some searching one may find the Brittle Road, which leads through the shadow-choked swamps, to the City proper.
A Renaissance dawns. A School of Art emerges.
Purple deer have begun to appear near the ruins of a fallen city, or other place of power. Hunting the deer is absurdly easy, as their coloration makes them easy to see. The heros prepare a feast from a freshly killed deer find out several hours later that the meat of the new purple deer is poisonous. This can range from cramps and vomiting to the truly sinister and lethal.
