The Iagoin were a race of semi-intelligent creatures that floated among the gaseous clouds of the gas giant Tyed Kant. All Iagoin were gelatinous and ovoid, with a single eye that could move around the surface of the creature. The creature's mouth was a conical opening with a series of filters, and they had long, paddle-like tentacles which were used for stability, movement, and defense. Iagoin could be as small as a few centimeters, or as large as sixty meters.
