Warriors, it is said in the codes, have a common Homestone. Its name is battle. Renegades of Gor, page 343

The population would be completely disarmed.
Possession of a weapon would be regarded as a
capital offence. Officers in the Warrior Caste and their
families were to be impaled, and in the population at
large every tenth man would be executed. The
thousand most beautiful women of Ar would be given
as pleasure slaves to Pa-Kur, for distribution among
his highest officers. Of the other free women, the
healthiest and most attractive thirty per cent would
be auctioned to his troops in the Street of Brands, the
proceeds going to the coffers of Pa-Kur. A levy of
seven thousand young men would be taken to fill the
depleted ranks of his siege slaves. Children under
twelve would be distributed at random among the
free cities of Gor. As for the slaves of Ar, they would
belong to the first man who changed their collar.

usually of the caste of Warriors. In a sense, given the
cruel selections undergone by his forebears, he has
been bred to his work. In his blood there is the spear
and war. Fighting slave of Gor, Page 180
