A buzzing sound fills the air above lonely desert dunes. The crescent moon illuminates a glistening procession of flying creatures. A raiding party of arthrops is heading towards a nearby oasis. The bizarre insect-like humanoids break formation as their leader touches a crystal in his throat. Moments later, shouts break out in nearby tents as the raid begins.

Hive Hierarchy. Arthrops have lived in the desert for thousands of years. They have a strict hierarchy and the queen is their supreme leader. The hive lives in an extensive system of hidden tunnels underground. Their queen is heavily protected by an elite group of guards.

Desert Warriors. These unusual creatures fashion their weapons out of items from the natural world. Remains of giant insects, plants, and anything stolen on raids are used by the resourceful humanoids. They know every inch of the desert world and use the terrain to their advantage.

New Voices. Arthrops used to speak in clicks and other natural sounds. Chaos tore apart their close society until healing crystals were found. Magical energy from the gems gave the arthrops a new voice and immunity against being charmed.
