As you near a cell with prisoner's remains in a yellow indicator will appear on the mini map. You can earn an [[achievement]] if you free them in 2 minutes or under (details below). Once you have freed them you will need to seek out the [[Warden]] who can always be found at the centre of the level at the crossroads. He is pretty slow so easy to avoid. He possess [[Jailer]] (as you'd expect) and [[Molten]] affixes but still, if you're the appropriate level here he and his few minions ([[Savage Fiend]]) shouldn't present a problem.
