Necrotech world.

The auction continued at a steady pace, showcasing an assortment of rare artifacts, some more interesting than others.

Rex and Cleo bid occasionally; she won a rare rock from a bioluminescent world that glowed faintly in her hands, and later, they snagged a blueprint for a robot bird. That blueprint, oddly enough, turned out to be the most expensive item they'd bid on nearly two million credits.

Rex couldn't hide his surprise. He glanced at Cleo, who was examining the blueprint on a screen, her eyes lit with fascination. Apparently, her affection for those little mechanical birds was stronger than he'd thought.

Rex made a mental note to hunt down more blueprints on his future travels; clearly, they'd make for good gifts.
