As usual, here a few pictures which I think accompany the story well.

They are not exactly what I imagined, but they will do.

*I do not own any of these, they are from Pinterest.

The last one shows the other two castles mentioned in the story apart from Bran-- Poenari Citadel (the ruin) and Hunedoara (Castelul Corvinilor), with as many turrets and towers as Hogwarts 😄
