The shark is the most efficient hunters in the realms. This has empowered the Shark Spirit, to become the Beast Hunting Spirit. This powerful spirit has bound elementals of various kinds and places with a shark imprint. These bound spirits spawn new shark races: land sharks, sand sharks, sky sharks, and as for here, The OcrheMaws.
The Ocadian Desert is a desolate place. The spirit of the land has been crushed, changing the region from a series of islands with evergreen forests and animals in a shallow sea, to one of the most inhospitable places on the Sphere.
“Don’t be a Yak.” A common Ocadian saying.
The ochre sands stretch for miles around. Something kicks up the dust. It’s a yak. A desert-yak. It ambles slowly, nuzzling the ground for the low-growing shrubs. The ranger freezes. “Stay very still,” he warns. “Don’t move at all.” “What is it?” you ask, breathlessly. “It’s the most dangerous creature in the whole Ocadian desert. And it’s about to eat that yak…”
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.
