Stinging Swarm (lore)

The deserts of Kehjistan are majestic, expansive, and...full of stinging swarms of insects. They may seem a minor nuisance, but these vermin carry numerous strains of pestilence. One of them was trapped in my boot once, and my foot swelled up to the size of a melon before the infection cleared! What horrible creatures! -- Abd al-Hazir
