“ 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.”
“ Oazduke's Vengeful Head.
The head haunts all headsman and executioners.
A floating, bloody head, long separated from its body, is a particular legend among a very particular group of people, executioners, specifically those that chop heads from a block for a living. It was that infamous highway robber, Oazduke the Vengeful, who when finally captured and put to the axe, screamed his foul hex, seconds before his head flew off.
'You will know it is me when I'm through
A curse on your ilk and on you!
May my severed head haunt you eternal
Frightening you headsmen infernal!'
Years later, not one but two(!) weary, puffy-eyed, spooked, headsmen, haunted day and night by Oazduke's insufferable severed head, approach the party cleric in order to hire him to exorcise the ghost head once and for all.”
