It's the middle of the summer and Louie has taken a job as a porter. Ila takes advantage of this, and while out with her on the job, he notices it begin to snow. Returning to the Guild, Ila gets a letter from Master Banarl, a magician who retired to the Tower of the Four Great Magics to complete his weather control research.
He asks the group to go with her to the tower to investigate. Along the way, the group meets the elf, Celecia, who joins them. But the road won't be easy with blizzards and demented nature spirits standing in their path.
