House seed
From Jenny Everywhere Wiki
Just before the Fall of the Strange and Wonderful House, Jenny Everywhere retrieved a House seed from the dying House.
It appeared as a miniature replica of the original House, no bigger than a Christmas ornament. She showed it to the Dragon who was the sole other witness of the House's Fall before pocketing it, thinking that it would come in handy one day.
