If you want to know what the heck guards do to prisoners, they lock 'em up in cells. Just like today (almost), they are hooked on chains that hang or whatever you call it. The people who get locked up are called "slaves". Slaves are people who work and are traded for one and another. They were brought to England by forse, and if they didn't do anything right for their owner, they would get killed. Now days, slaves are iligle in most contries, but they may bring it back. You might not know.
