From the records came a warning. When the Earth becomes too electrically charged, the magnetic fields decline.
The poorly expressing magnetic, which is the feminine components, and the over-emphasized electrical components – which is the masculine – attracts calamities. By grounding the electrical charges, life flourishes and calamities are either delayed or averted.
When the Whale Clan came to the island of Nanathestu Madal, they found in the ruins left behind by the Ancient Ones, writings on how to ground the electrical charges of the planet. They used this to delay the catastrophe long enough to prepare the records for those of the future to find, and so that they could change their frequency to match that of Nanaktu.
The Ancient Ones had created lagoons. They stocked with electrical eels and had built structures around them to ground the electricity. Where people around the Earth had knowledge of this, towers and obelisks were built to act as grounding rods. This caused the fields around them to flourish, and the area to be less prone to weather disturbances.
