Order of the Black Sun

The Order of the Black Sun was an group that waged a time war against the Time Lords, the first time war that the latter group ever fought.

Overview
Though [time travellers from thirty thousand years in the future began the war, they possibly also existed in the very early years of the Rassilon Era, as they took part in a conference on Desrault which included the Sontarans. (DWM: Black Sun Rising)


 * Unless the Time Lords and/or the other delegates had time traveled to get to the conference.

Several different species, some humanoid, others not, made up the Order. They wore capes and black unitards with a logo on them. (DWM: 4-D War, Black Sun Rising) They used hand-held black orbs as the focus for blasts of power. (DWM: 4-D War)


 * For details on this, see separate entry. With Order of the Black Sun a relatively minor power in the universe, it seems the Time Lords eclipsed them in significance.

Behind the Scenes
Alan Moore mentioned that he intended the Order as a reference/tribute to DC Comics' Green Lantern Corps.
