Brundisium

The Red Caste is the lowest of the five High Castes of Gor.
All members are taught the Second Knowledge.
All males of the Red Caste will also be taught standard weapons and
dress of Warriors of Gor, the spear, short sword, shield, and helmet.
A Warrior of Central Gor must have a Homestone as well,
to be without one is to be considered Outlaw.
Outlaws may not be sponsored to the Caste, though a member of the Caste may later become a outlaw.
Other lands are considered to have their land as a Homestone.
Each City or land will have a Rarius Caste Council 
who is responsible for training and
affirming new members to the Caste.

"The caste system was socially efficient,
given its openness with respect to merit,
but I regarded it as somehow ethically objectionable.
It was still too rigid, in my opinion, 
particularly with respect to the selection of rulers from the
High Castes and with respect to the Double Knowledge.
But far more deplorable than the caste system 
was the institution of slavery.
There were only three statuses conceivable
to the Gorean mind outside the caste system:
slave, outlaw, and Priest-King.
A man who refused to practice his livelihood
or strove to alter status without 
the consent of the Council of High Castes was, by definition,
an outlaw and subject to impalement."
Tarnsman of Gor (Chapter 3).
