Excerpts[]
- It was crucial that one giant must, at all times, be sat atop the tallest mountain, a long-forgotten peak in the north. There, he or she would gaze tirelessly into the black, guarding the Earth from anything that might threaten from above. Any young giant could be summoned as guardian, a duty that could last for millennia.
- "Legend says that the last guardian to serve was this fellow: Jorgen." (Hilda)
