The Dark Eye is an immortal intelligence bound in a mystic staff, a legacy of Corvus. From its hidden place, it influence the world for its own purposes and the purposes of its Dark God.
In the depths of a forgotten dungeon lies a staff containing immense power - and a cold, calculating mind, seeking to rule the cosmos…
A well worn plain staff made from oak. Gives who holds it the power to track as a wolf.
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.
