Thals

The Thals were one of the humanoid races which originally inhabited the planet Skaro. Thals looked much like Kaleds and humans, though they could be distinguished from Kaleds by their blond hair and light eyes. During the Thousand Year War, Thals were just as brutal as their Kaled enemies. 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. After the war, the Thals committed themselves to pacifism. 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 again adopted a militaristic way of life, though only, it seems, against the Daleks.
