Starting February 4th, 2020 Destiny players will start a new, mysterious quest called the “Empyrean Foundation.” According to the data mine, players will restore the Lighthouse on Mercury through the foundation. A data-mined, in-game message then reads “with the restoration of the Lighthouse complete, Trials of Osiris and more will return in Season of the Worthy.”

More updates to be found as we find them.
