Kadabra:  Located at Barsoom’s North Pole,  this is the capital and largest city of Okar, the land of the yellow Martians. The outer wall of this enormous domed city of Kadabra is 100 miles in circumference.   The evil and wicked Jeddak of Jeddaks of the North, Ruler of Okar, Sallaneus Oll was not only a devout follower of the Cult of Issus, he also had religious reverence for the apt. 

 

“I was surprised to note that all the guards with the hotel at which we stopped were red men, and on inquiring of one of them I learned that they were slaves purchased by the proprietors of the hotels from the government. The man whose post was past my sleeping platform had been commander of the navy of a great Martian nation; but fate had carried his flagship across the ice-barrier within the radius of power of the magnetic shaft, and now for many tedious years he had been a slave of the yellow men.  He told me that princes, jeds, and even jeddaks of the outer world, were among the menials who served the yellow race.”
