Legacy of Yesteryear was a comic strip published in TV Century 21.
The Daleks explore Skaro, intent on learning its secrets. In the North, near the pole, a Dalek ship fires at a mountain to analyse its composition. The blast activates long-dormant machines deep inside the mountain, which begin to thaw three human Daleks from suspended animation.
The Daleks are exploring their planet to bolster their defences. They find precious stones in the mountains, desert creatures in the desert and mutated jungles that they clear with fire. At the North Pole they apparently find nothing, but awaken long frozen beings, three of the first Daleks, laying frozen deep within a mountain.
Upon waking, the original Daleks look around at their descendants and find they are cold creatures without conscience.
One of the Daleks, Yvric, betrays the other two and goes to try and give information to the Daleks. The Daleks, thinking he is an android, exterminate him.
Lodian then decides to show Zet what he discovered before they were frozen; a planet teeming with life, mineral wealth that is always learning and improving; Earth.
Zet knocks out Lodian and offers him to the Daleks so that they might become masters of the universe.
Lodian escapes the Daleks and Zet and finds himself to a rocket ship that he hopes to use to travel to Earth to warn them of the Daleks. But before he is able to launch Zet and the Daleks find him. Deciding that the risk that the Daleks find him and discover about Earth he makes the supreme sacrifice, blowing up the ship killing himself, Zet and several Daleks that were close by.
