I'm currently working on a historical fic that takes place in the early sixteenth century, and I've hit a bit of a brick wall. My characters have to get back to Hogwarts, and King's Cross hasn't been built yet. Trains don't even exist.

How would sixteenth-century witches and wizards travel to Hogwarts without the Hogwarts Express?
In the series, they all meet up in one Muggle place (being King's Cross) and then are mass-transported to the school via train. However, without cars, it would be difficult for wizards and witches from all over Britain (including Muggle-borns) to all congregate in one specific place before going to Hogwarts.

I've considered having the students picked up individually, maybe by Thestrals or perhaps trained dragons, seeing as this is taking place before the outlawing of dragon breeding at the Warlock's Convention of 1709. Neither of these appeal to me very much, though.

Any ideas?

Peace,
Virgil
