 By testifying, Vlad commits the ultimate sin in the Organization, ending his career and branding him for death.Testifying in public, "under the orb," (which can detect falsehoods) is what ultimately sets the Jhereg Council against him.His previous acts of threatening the lives of his immediate superior in the Jhereg, Toronnan, and his boss' boss, Lord Boralinoi, as well as the Jhereg representative at court, Count Soffta, got the Jhereg to put out a (non-Morganti) contract on him but, given the nature of the organization, Vlad would have been "forgiven" had he "won" his war.
