The Dragon Isles consist of no less than thirty or so separate islands, of varying sizes, in a fifty-mile chain running on an approximately north-south line about thirty miles off of the eastern coast.
When mans’ smallest, and most deadly, enemy strikes the world is thrown back into a darker, more primitive age.
A post-apocalyptic setting for any system.
A pleasant little grove with an unusual resident
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.
