Consider a visiting slave merchant

[miki151]

Would allow buying prisoners for a limited amount of time

Could I suggest that his prisoners appear in the immigration panel until he leaves your territory. It would be easiest for players to buy slaves with gold by clicking on the prisoners in the immigration panel and to have the cost in gold shown like other immigrants have.

Great idea.

Could I also suggest that it reuse the existing immigration.txt system for moddability. Entries could go into immigration.txt and be added to suitable keepers in player_creatures.txt

Something like this maybe:

"travelling_slavemaster"
{
    {
      ids = { "HOBBIT_SLAVE" }
      traits = { PRISONER }
      no_auto = true
      requirements = {
        { 0.0 TravellingSlavemasterPresent }
        { 1.0 CostInfo GOLD 20 }
      }
    }
    {
      ids = { "CENTAUR_SLAVE" }
      traits = { PRISONER }
      no_auto = true
      requirements = {
        { 0.0 TravellingSlavemasterPresent }
        { 1.0 CostInfo GOLD 10 }
      }
    }
}

This would be cool
