A forcefield suddenly passes over their heads, and over the walls, leaving them trapped inside the circle. Now on the wall above them an old woman steps forward. It isn't her age or haggard appearance that makes her so hideously ugly, but the energy about her, the pure malice that pours out from her.

Her malice is why she was chosen for the role she's in.

"My name is Granny Goodness, and I will be administering your final exam. This final test is to weed out the weak and any naughty children that try to infiltrate our ranks for their own purposes."

She wags a finger at them.

"Being willing to die for the cause is not enough. You still have to fight those who would oppose us. Very few of you likely have such skills already. Fortunately, Granny can teach you. Granny has braved the terrors of the Necropolis of Apokolips to learn the old ways from those long gone."
