One Dalek Time Strategist became a major player in the Last Great Time War. He sent Lara Zannis to Earth to capture the Shadow Vortex. The Strategist wanted to invade the Earth in order to destroy it and stop the Doctor from meeting his companions hopefully erasing him from the timelines. (AUDIO: The Shadow Vortex)
The Strategist sent the Daleks to Rovidia to capture Cardinal Ollistra, intending to steal her knowledge of Time Lord secrets. The Sontaran Fesk tricked the Strategist into meeting him and took the Strategist prisoner, disarming him. The Stratagist was placed with Ollistra where they talked about the starting of the War. (AUDIO: The Eternity Cage)
The Strategist ordered the destruction of the Rovidian fleet after the Doctor left the planet. The Strategist believed that the Doctor had given the Daleks the means to win the war. It used Heleyna to gain access to the Eye of Harmony chamber within Vassarian's Battle TARDIS. It planned to use the Dalek Time Squad to attack the Eye and cause it to collapse the Eye and destroy the Time Lords. The Doctor stopped his plan by destroying the Eye of Harmony Chamber.
