A sizable hydrogen-nitrogen gas giant just on the far side of its pale yellow star's frost line, Dranen is known for its spectacular storms. At least three persistent observable "spots", actually cyclonic and anticyclonic storms, have lasted for over 544 years--significantly longer than Jupiter's Great Red Spot. The largest of these spots, the Ishna, has consistently held a diameter over three times that of Earth.

Dranen has 44 moons. Two of them are of special interest to the Citadel Committee on Habitable Worlds. The first, Arvuna, is a life-bearing world that has already been colonized. The second, Alahya, is slowly being terraformed into an ammonia-based world for volus populations.
