The Watchtower is the access point Light Hope uses to access Etheria's mainframe of First Ones' tech that runs through the planet.
Description[]
The First Ones created this watchtower sometime between the landing of Etheria and The Heart of Etheria project. It was one of the keys to activating the Heart of Etheria.
Mara destroyed the Watchtower 1000 years ago to keep Etheria safe from the First Ones activating the Heart of Etheria, severing Light Hope's connection to the planet. Since then, Light Hope worked at only a fraction of the power she had access to. To Light Hope's instruction, but not fully knowing about the Heart of Etheria project, Swift Wind and Adora repaired it in "Ties That Bind", forming a sacred bond and successfully repairing Light Hope's functions with it.
