“ Along the sluggish Vanne River, the banks are lined with thick stands of tall bulrushes. These areas of wetland are considered ill-omened by the locals, for they hide the skeletal remains of thousands of grazing animals, washed downriver in a terrible flood decades before.
Adding to the uncanny reputation of the place is the occasional undead cow or goat that lurks there. The product of a necromancer's experiments some years before, these relatively harmless undead wander the area at night, startling livestock as they attempt to graze with them.”
“ A few musicians play their instruments and a beatiful maiden dances to the music. Wonderful to look upon, you surely will spend a few coppers, will you? In addition, two thieves move through the on-looking crowd. 'Spare the coppers - loose the silvers!' your father used to say.”
“ On a location with numerous webs, and at least one big spider, there is a something inside a cocoon. It is humanoid in shape, still moving. If the heroes free it (not before they kill or drive away the spiders), they meet a ... zombie!
The poor zombie wandered the dungeon alone, and tried to kill a big living creature (= a spider). The spider used the usual treatment, even if this victim did not look tasty. The zombie can be easily killed as any other zombie. It got but several doses of spider-poison, so can be something worth if it is extracted. You can mention to a druid or ranger the fact the spider had no poison anymore.”
