Gaden-Ko is the son of a sculptor and a former Voss commando who was maimed by the Gormak when Gaden-Ko was small. As is Voss custom, he was raised by his grandfather‒Dajan-Ko‒who soon noticed the young Gaden-Ko's uncanny intuition. This insight allowed him to aid Voss commandos by predicting where Gormak patrols would be. Thus marked as a potential Mystic visionary, he has spent years at the Tower of Prophecy studying and preparing to go on his pilgrimage.
Gaden-Ko's generation is the first to grow up in a Voss-Ka where alien outsiders are a common sight. He has always had an interest in these foreigners, even developing a friendship with the Republic ambassador. Perhaps because of these outside influences, Gaden-Ko is seen to be rather impulsive and impatient compared to other Voss.
