The devil was in the center, when Dante finally entered. He was frozen too, and he was stuck there fast. His body they climbed down (I guess that’s how they get around), somehow wound up in heaven, to Dante’s goal at last.
The treacherous were found, in a circle that had “rounds,” in the lowest pit, thats circle number nine. Frozen in ice they lay, and frozen they shall stay. Cold, unmoving now and til the end of time.
