Fan Casting Doctor Who The Lion Hearts (2015)

The Doctor traced a signal from the Dalek Time Strategist to Atherea and decided to assassinate it, encountering Commodore Tamasan who was on a mission of her own to the planet. After Tamasan’s contact was erased from history, they completed her orders by making contact with a squad of Gallifreyan special forces who had been raised in secret on the planet to fight the Dalek presence there, which was using a time eradicator to assassinate soldiers vital to Dalek losses, turning the tide of recent battles. The Doctor used himself as a distraction to enable the squad to find the Dalek base and discovered the eradicator was one of the Strategist’s engineers, now existing as part of the Vortex and able to see possible timelines.
