Hakol
From Tardis Wiki, the free Doctor Who reference
Hakol was a planet located in the Rifter star system, and the home planet of the Hakolians. Since this race invaded planets for power sources, it might be that Hakol had been stripped of all resources. (TV: The Awakening) As the Hakolians used Terileptil prisoners to mine tinclavic on the planet Raaga, it may be that Hakol once had tinclavic. (TV: The Visitation)
