"So my son... you are asking about this Solaria? I say a fairytale, and a bloody one it is... yes. Since the Prophet came and gave us the View and the Way we are dreaming of it. But the dream turned to nightmare quickly enough..."
Letter of the Heretic
The Heretics were banned from the Heaven for spreading rumors against the View and the Way. The prosecution became severe in 4th century and culminated in exodus of 2385 With two old freighters they took refuge in Miners Guild asteroid base on Ceres. They became highly involved in advancing the Guild technology. Also from their rows came squads of top genetically enhanced soldiers known as Protectors.
