====Siege of Terra====Valdor fought in defence of Mankind's homeworld during the [[Siege of Terra]]. During the Siegebattle loyalist marines who witnessed the Captain-General in combat, he saw him reave through traitor marines as easily as they would against ordinary humans and weaker xenos. He also deployed [[Amon Tauromachian]] to investigate apparent [[Daemonic]] activity in the [[Imperial Palace]]. When Amon asked what should be done to [[Euphrati Keeler]] and her proto-[[Imperial Cult]]ists, Valdor ordered that they remain unharmed as part of Malcador's plan to use them in the fight against Chaos.{{Fn|12a}} After the fall of the [[Lion's Gate Spaceport]] he helped lead the defense of the [[Colossi Gate]] alongside Jaghatai Khan and Raldoron, fighting against swathes of [[Daemons]].{{Fn|14}} After the escape of [[Basilio Fo]] from [[Blackstone Prison]] Valdor saw the mad scientist a threat big enough to warrant his own personal attention, and he hunted the prisoner throughout the Palace.{{Fn|19a}} He eventually saved Fo from a roaming [[Night Lord]] and decided that the human's supposed anti-Astartes bio-weapon could be of service to the Emperor.{{Fn|19b}}

Later Valdor was summoned to the Emperor's side during the final teleportation attack aboard the ''[[Vengeful Spirit]]'', and he left Basillo Fo and his weapon in the hands of his own Custodes.{{Fn|17a}} During the battle loyalist marines who witnessed aboard the ''Vengful Spirit'' Valdor became separated from the Emperor and he and his Custodes found themselves in a dark abyss surrounded by [[Daemon]]s. Part of a trap by Horus to drive the Captain-General in combatto torment, saw it made him reave through traitor marines feel something close to fear for the first time as easily he realized he could not fulfill his duty. Nonetheless, this did not stop Valdor's killing duty in the slightest as they would against ordinary humans and weaker xenoshe slaughtered his way through hordes of Daemons. To confirm that he had indeed been teleporated to the ''Vengeful Spirit'', Valdor plunged the [[Apollonian Spear]] into its floor to reveal its identity. {{Fn|17b}} After the Siege of Terra, Valdor met with the newly arrived Leman Russ. While Russ was distraught and pessimistic of what had befallen the Imperium and Emperor, Valdor expressed confidence that the Master of Mankind had foreseen all that had transpired and planned accordingly. Secretly however, Valdor is unsure if this is true.{{Fn|10}}
