A subspecies of scorpion that lives in dry areas like deserts and wastelands. The poison in its tail is virulent, and even the slightest amount of it can bring down the largest of beasts. They are basically nocturnal, so during daylight, they are often found burrowed under the sand in hiding, or shaded behind boulders. Most instances of reported casualties during daylight comes from people inadvertently entering a desertpede’s territory.
As a summoned, template, creature, this creature has several changes. Anything noted with  is what it gains from the template associated with the summoners’ alignment. Divine is always listed first, and Unholy afterwards.
