Tash's Country

Tash's Country is where all species went to if they rejected Aslan. Tash's Country held a dark dismal place for its denizens, and it is where Tash himself ruled. It is plausible that characters such as Ginger, Rabadash, Miraz, Lady of the Green Kirtle, and everyone including Jadis herself were placed in this country.

Note
It should be noted that C.S. Lewis clearly depicted Tash's Country to be the Narnian version of Hell. The polar opposite of Heaven is Hell and C.S. Lewis clearly states that the opposite of Aslan's Country is Tash's Country.
