History

(NA: GodEngine) The Guild of Adjudicators itself would continue until at least the 30th century. (NA: Original Sin)

Eventually, the Order passed its prime and dwindled. One Knight of the Order Orcini, reluctantly made his living as an assassin and of Orcini's squire, the Order had seen better days. Knowing he would die within minutes after setting off a bomb to try to kill Davros, Orcini gave his medal from the Order to the Doctor and requested that he return it to them. (DW: Revelation of the Daleks). The Doctor said afterwards that, searching through Orcini's time, he never did find any trace left of the Order. (NA: Lucifer Rising)
