DOWN IN A HOLE! Sabretooth went into the Pit, sentenced to an eternity of torment. Sure, that sounds like hell, but maybe that's where he feels most at home. What's he been doing down there? What secret deal has changed his fate forever? And what if he's not alone? Award-winning novelist Victor LaValle teams up with amazing artist Leonard Kirk to bring us the story of what lies beneath Krakoa.

MAN IN THE BOX! Professor X promised there would be no prisons on Krakoa. Sabretooth was the first in the hole, but now he welcomes five more mutants to his own private hell. What laws did they break? Are they ready for what they’ll find? No. No, they’re not.

THE GREAT ESCAPE! Sabretooth and the other exiled mutants have stopped fighting each other long enough to start working together. They might not like one another, but they all want out of the Pit. You'd think their biggest obstacle would be the Professor or Magneto…but no. The greatest obstacle will be one of their own.

CALL IN THE CAVALRY! Even the best-laid plans fail. But above ground there are other mutants who've learned what's happening in the Pit and they aren't too pleased with the injustice of their fate. If Sabretooth and the others couldn't break out of the Pit, maybe someone will just have to break in.

ALL THINGS MUST END… …but how? Sabretooth has changed Krakoa but has Krakoa changed him? No one gets away clean in this story. And maybe there are fates even worse than the Pit.
