From the Ra Contact: An angelically positive wanderer who was aided by Confederation sources in bettering the existence of his fellow people; attempted to give to the planet the infinite energy of the planetary sphere for use in lighting and power; unfortunately, due to the vibratory distortions of third-density illusion, his perceptions of his fellow people became so distorted that his mission was hindered and in the result, perverted; information offered through him was experimented with for potential destruction (e.g., the Philadelphia Experiment).
