First, let me explain, why no kajirus, are found in the Palace. Kajirus are male slaves. Male slaves of Gor, were looked down upon by Free Gorean Men. Simply because of the weakness, not to live up to their Gorean Birth right. Some of the Make slaves, were simply Free Men, of whom, like Tarl, lost their Honor, and have a task to earn their Honor Back. Other Male Slaves were there for a specific purpose.. such as the Lure Slave, used to draw a Free Woman into couching. Most Male slaves however.. were workers.. laborers..helping build, unload ships, and doing heavy lifting. The Palace is a Building, in which no Male slave would exist.. with simple exception to be a slave of a peasant perhaps delivering something.
the Lure Slave.. would not be within this Palace.. a Tyros is Known for its Raising of Proper Free Women in its High Terraces.
Fighting slaves.. often were Free Men.. collared because of a Crime, or being declared dishonorable by their Ubar. These men.. still held rights of Free Men.. however.. were mostly "tenders" to Honorable Free Men.
Kajirus were never silk slaves.. and it is why.. kajirus in Tyros.. will not be trained as such.
