The Chronicles of Hallowdwell
- Necrotic plague. Clouds of putrid brown fog (“miasma”) roll into an area. Those who breathe of it suffer increasingly bloody coughing spells, fever, retching, wasting of the muscles, and in all likelihood, death.
- The undead army. Those who die of the necrotic plague, if not immediately cremated, rise as the walking dead: skeletons, zombies, ghouls, and other foul beasts. Sometimes, even those whose bodies are quickly disposed of instead manifest as spectral undead: ghosts, spectres, wraiths, and the like. Rather than wander in search of flesh to feast upon, or haunt any particular area, these undead seem to band together as if commanded by a greater intelligence, and work to spread the boundaries of the plague lands.
- Crop blight. The necrotic plague affects not only humans and animals, but vegetation as well. Arktfar has become a blasted land of withered trees and dust-swept fields, and Ostlund has begun falling to the same fate.
- Waves of other disease. With rotting corpses roaming the land in an apparently concerted effort to bring ruin, more mundane diseases normally kept at bay by hygiene and proper burial run rampant as well. Survivors of undead attack frequently contract gangrenous infections, pneumonias, etc. even if they did not breathe the miasma itself.
- Mearis Lord de Thuin, and his manor in southern Arktfar. The first clouds of miasma poured out from his estate, some time after he went into seclusion following the great Treaty between Arktfar and Allandria. The peasantry speak his name only in fear, believing him to be the necromancer responsible for the plague.
