In a campaign I'm developing, elves have been enslaved by a race of lizardfolk/yuan-ti for generations. The lizardfolk/yuan-ti have kept the elves in 'concentration camps' in order to maintain control over them and put them to work for their reptilian society.

I need a name besides concentration camp for the campaign, something with more of a fantasy feel than a world war II feel.

Thanks for the help.
