Across the Darkened City (audio story)

 was the second story in The First Doctor: Volume Two.

Publisher's summary
On the planet Shade, The Chaons, an invading race of strange, amorphous creatures that ravenously absorb energy, have reduced the city there to a desolate ruin. Separated from the First Doctor and Vicki, Steven has to join forces with an unexpected ally to find his way back to the TARDIS. Ahead, lies a nightmare journey through the dark - a test of endurance and trust.

Journey into Night (1)
Steven is among a group of prisoners held captive by the Daleks, separated from the Doctor and Vicki on Entropica after a failed attack. Despite Steven's protest, one woman is killed for being too weak to work. The rest are scanned prior to robotisation. A prisoner revolt instigated by Steven and Mettie sends the ship crashing on the planet Shade. One Dalek is damaged and so the other two destroy it because of its "deformity". One of them then proceeds to exterminate all of the prisoners, but is itself destroyed by the last Dalek, Genetic Variant Two-One-Zero, before it can kill Steven. Steven and Two-One-Zero are the only survivors and their only hope of escaping the planet is a transmat left by the Daleks on a previous invasion. Two-One-Zero knows the codes which can return him to Skaro, but with his drive units disabled in the crash, he needs Steven's help to traverse the ruins of the dark, vast city, which is swarming with vicious Chaons.

Steven loads Two-One-Zero onto a cart which he can pull, but the damage wrought by the Dalek invasion has left many roads impassible. They travel through a warehouse occupied by a Chaon to bypass one obstacle. At another, it begins to rain. A bolt of lightning strikes Two-One-Zero, leaving him immobile and unresponsive. Steven knows that without him, he will be trapped on the planet.

The Chaons (2)
Two-One-Zero revives, using the charge from the lightning to repair some of his systems. As they continue into a street of buildings full of Chaons, Two-One-Zero instructs Steven to turn off his torch, ostensibly to save its charge or not to attract Chaons. However, Steven is able to make out in the darkness a mass grave of Shade's inhabitants slaughtered by the Daleks. He realises this is the real reason he was ordered to turn the torch off. Disgusted and furious, Steven threatens to destroy Two-One-Zero with a magnobomb he salvaged from the ship, but Two-One-Zero returns a warning shot with his gunstick. He claims he is "better" than other Daleks, and Steven calms himself down. As Chaons catch up with them, Two-One-Zero abandons his casing, which the Chaons devour. Steven carries the mutant and its translator device in a tarpaulin across a body of water and into the transmat station.

Without life support, Two-One-Zero is dying. He pleads to be sent back to Skaro, instructing Steven how to work the dais. Steven demands Two-One-Zero stick by the terms of their deal and give him the code for Entropica first. When a Chaon attacks, Steven places the mutant into a disused Dalek casing left in the station. It fights off the Chaon. Then he betrays Steven. Steven seeks cover behind the controls, knowing the Dalek wouldn't dare risk firing on them, and demands the code for Entropica. Two-One-Zero gives the code as 02943764 and Steven actives the control before he is fired upon. As more Chaons arrive, Steven receives contact from the Doctor, who gives him the code for Entropica. Steven notes it is different from the one the Dalek gave him. Quickly inputting the correct code before the Chaons devour him, Steven returns to Entropica and arrives at the TARDIS where he is reunited with the Doctor and Vicki, his real friends.

Epilogue
Despite almost being destroyed for returning to Skaro in a different casing, making him difficult to identify, Two-One-Zero is the only surviving Genetic Variant. As such, he is declared the superior Dalek and is placed in the emergency container. He then declares himself Dalek Emperor and, intrigued by Steven's behaviour, orders that the Daleks' prime directive is to discover the Human Factor so that their enemies can one day be crushed and the universe conquered.
