Giani'aga was a male individual who was known in the Gamma Quadrant for creating living objects called Giani'aga boxes. He made fifty of them in total; forty-seven large ones, his life's work, and three small ones before he died. Each box was worth large amounts of money, with the small ones being priceless.
In 2376, one of Giani'aga's small boxes was located among the stolen treasures that the Drang plundered. While the crew of the Even Odds were set on their retrieval mission, Jake Sisko found the box and took it with him. (DS9 novel: Rising Son)
