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.

He motioned them to aim towards the blight, the dark patch near the fields edge

The PCs are hired by undead to rid their village community of an invasive necromancer.
As the PCs make their way, wherever they are going, they spot two zombies. The zombies approach but before the cleric can turn them, one starts throwing coins at the PCs while the other pleads with them, unable to pronounce the letters "L" and "H" due to some missing gums.

Apparently, a small benign community of undead have taken residence in an abandoned village, living out their undeath as peacefully as the undead can. Recently, a malicious necromancer has invaded the village, and plans to enslave the entire populace with his malignant spells, raising a small army.
The PCs must battle the vile necromancer, even as he animates the very folks who hired the PCs in the first place, to slaughter them.
