Synopsis

An individual is transmatted onto a Dalek saucer and told that they've been designated the Dalek Warlord. They will lead Dalek troops into battle with inferior species such as Cybermen, Zygons, and Judoon. The Warlord must construct miniature Daleks for this conflict. The Daleks then detect that the Doctor is nearby, and declare that they must prepare for battle.
