Thal

Thals were one of two near-Human races which originally inhabited the planet Skaro (the other being the Kaleds).

Physical characteristics
Thals appear identical to Humans and Kaleds (DW: Genesis of the Daleks onwards). Previous to the Thousand Year War the Thals tended towards blond hair. (DW: Genesis of the Daleks). Afterwards, all Thals had blond hair. (DW: The Daleks, Planet of the Daleks) The Thals believed that, following the war, radiation had mutated them into perfect beings, though after a stage of advanced mutations. (DW: The Daleks)


 * Either they had also evolved to have much greater radiation resistance to Humans or Gallifreyans, or else they had very effective anti-radiation drugs, or both.

One account states that both the Thals and Kaled descended from humans transplanted from Earth to Skaro as an experiment by the Halldons. (RT: We are the Daleks!)

Earliest history
The Thals had written records going back nearly half a million years. Oral history and later records would describe the Thals as originally warriors, while the Kaleds (known to the Thals as the "Dals") were more orientated towards philosophy and science. (DW: The Daleks)

Thousand Year War


The Kaleds and Thals engaged in a Thousand Year War. Though they originally used advanced technology, towards the end of the war they were forced to use technology that was more primitive. By the end of the conflict, both Thals and Kaleds sheltered in domed cities overlooking a wasteland. (DW: Genesis of the Daleks)

The war concluded when Davros, a Kaled leader, gave the means to destroy the Kaled Dome to the Thals. They used this compound in the missile they sent to the Kaled city, and destroyed it. In "retaliation" for the destruction of the base, Davros ordered the Daleks to destroy the Thals. Led by a Thal, Bettan, Thals and Mutos joined together to fight the Daleks, who were trapped in the Kaled bunker after an explosion, defeated but still alive. (DW: Genesis of the Daleks)

Aftermath

 * An indeterminate length of time, longer than living memory, passed. One Thal suggested it was 500 years. (DW: The Daleks)

The Thals renounced violence and became pacifist farmers living in small bands on a less radiated plateau. They would not even engage in violence for self-preservation and showed no curiosity about the Dalek City or its inhabitants. (DW: The Daleks)



After a particular bad year for crops, the Thals were forced to move to the Petrified Forest near the Dalek City in order to look for food. Ian Chesterton, a companion of the Doctor, used moral blackmail to force the Thals, Alydon into particular, into putting together an expedition into the Dalek City in order to fight against the Daleks who intended genocide against the Thals. The Thals invaded the Dalek City, cut off the power, and so deprived the Daleks of the static electricity they needed to live. (DW: The Daleks)

Spaceflight era
The Doctor and Jo Grant met a taskforce of Thals on Spiridon where a small group, led by Taron, had landed to destroy a Dalek army massed on that planet. The Thals had, by then, reclaimed Skaro. (DW: Planet of the Daleks)


 * This event possibly takes place in 2540.

The Thals were said to have relocated to another homeworld, sometime before the Renegade-Imperial Dalek civil war. (DWM: Emperor of the Daleks) In their absence, the Doctor had Skaro destroyed. (DW: Remembrance of the Daleks)

In reality, a decoy world named Antalin had been destroyed. The Thals were known to have survived past Antalin's destruction, and fought the Daleks on Terakis. (EDA: War of the Daleks)

The real Skaro was destroyed in the Last Great Time War between the Daleks and the Time Lords. (DW: Daleks in Manhattan)

It is unknown what became of the Thals after this point.


 * It is possible that the Dalek Prime was lying in War of the Daleks, and his story about Antalin was false. If Skaro was the planet featured in Destiny of the Daleks rather than, as the Dalek Prime claimed, Antalin, then the Thals had apparently left the planet by that time.

Culture
During the Thousand Year War, Thals were equallly as brutal as the Kaleds. They had no qualms about using the slave labour of Kaled prisoners and Mutos to build the neutronic missile, even when they knew the radiation from the missile would kill the slaves. (DW: Genesis of the Daleks)

As noted above, after the war, the Thals developed into a peaceful people concerned with knowledge and living in small bands. (DW :The Daleks)

Centuries later, they revered the Doctor and his companions as heroes and referred to the prior event as the First Dalek War. Turning full circle, they had once more adopted a militaristic way of life, though only, it seems against the Daleks. (DW: Planet of the Daleks)
