They were the viziers, prophets and cunning advisers of the First Age. Toward the end of the First Age, a prophecy came to them that warned that without action, Creation would fall to darkness. Seeking to save the world, the Sidereals looked into the future and saw two options: attempt to reform of their maddening kings, or destroy the Solar Exalted and raise up the Dragon-Blooded in their place. The Sidereals, possibly under the effects of the Great Curse laid upon them by the Neverborn, elected the path that offered a guaranteed future for Creation. As such, they orchestrated the end of the First Age, known as the Great Usurpation.
