Inadvertently let her dungeon captives escape by taking out bricks from their cell walls.
She's not going to be happy with you.

It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air –
There's the rub, the task.
– Virgil, The Aeneid (Book VI)
