After being beckoned by his father, a young man uses mystical powers to ascend from a spaceship to a cloud city, a process that leaves him in deep disarray. His father reminds him of their family ties, which promptly calms him down; he then proceeds to graft an organic hand on his son's stump and unfreeze his closest friend. Then, in direct opposition with his orders, he gives control of the cloud city back to its inhabitants, and sends off the young man with his friends. Despite the show of goodwill, the young man and his friends, with a myriad other rebels helping them, brazenly decide to capture a frozen planet from the official government, establish a base, and go into hiding, much to the displeasure of the young man's father.
Also, the young man goes out of his way to drive a small green hermit living in a swamp into insanity. What a jerk.
