Congratulations - you did it! You repaid your debt to society, and you are now allowed to rejoin it. No longer are you required to mindlessly roam the prison's cell blocks: You are now a free man, and you are even less restricted than ever! Although Server Rules apply at all times, Prison Rules don't apply in the Free World! Go have fun; kill a pig, build a mansion, or make BP quicker than ever!
The only part of the prison that is restricted to Frees only, Free Spawn contains many basic things a free man would require - warps to every cell block in the prison (with the exception of D Block), a warp to the Free City of Omega, a bank, and warps to events. Near the spawn is also where Chaos players goto reap their benefits!
