Some things about slavery...
There are three types of slaves: The Common, The Skilled, and The Prodigal.
A Common slave costs 100 gold coins in the slave market. Upon purchase, they are educated in basic arithmetic, literature, are fairly athletic, and have no special skills but basic wilderness survival skills (more on that later). Over time, however, they can become skilled, and then you can sell them for a higher price than 100 gold coins.
A Skilled slave costs 500 gold coins in the slave market. They, like The Common, are educated and athletic, but they are skilled in
one thing, whether it be fighting, blacksmithing, food preparation, carpentry, basic potionology, etc.
A Prodigal slave costs 10,000 gold coins, and are the champions in what they do. There are only seven Prodigal slaves in the Island of Murder (I will make a character sheet for each and every one of them.).
((Do you wonder what prodigal skill this sexy female slave has? lol. Character sheets for the seven Prodigal slaves are coming up.))
