There’s something about scorpions that screams “Danger.” Their silhouettes alone are unmistakably threatening. Now inflate them to Large size (or larger) and they become truly terrifying (since they can easily be scaled to your players’ level).
The yellow-skinned Orthari elves are not drow. Nor are they evil per se. But given their xenophobia and their rabid worship of the Stone Scorpion, trespassers who feel the sting of their envenomed blades—to say nothing of the stings of their giant scorpion pets—can be forgiven for making assumptions.
Deadfall scorpions are aptly named. After they ransack jungle villages, keches will often chop down trees to create deadfalls, forming habitats for the Huge scorpions. The vermin then make short work of any stragglers or escapees the keches might have missed.
A chronoclysm sends adventurers back in time to the Age of Insects. When they awake in a daze on the primeval shoreline, they are immediately attacked by giant sea scorpions. Worse yet, their presence arouses the interest—and horror—of local qlippoths, who have never encountered humanoid souls before.

Wizards of the Coast’s Eberron setting should get a nod here for making scorpions (and drow) new life.
Backlog alert: Apparently today is ScorpionFest, since I’m also writing up the black and cave scorpions.
These scorpions will not, however, take you to the magic of the moment on a glory night.
