I mean, is it permanent or do I have a plan for getting back to now? If it's permanent, the gun and bullets because fuuuuck that. I'm not living in medieval times as a woman. Even if pretty much all of history wasn't a horror show for women, I have like, zero useful skills and I'm pretty sure I'd only understand about half of what people were saying because Old and Middle English were a total suckfest (and that's if I didn't end up somewhere they spoke fucking French or some shit).
If I'm just there for tourism, none of it. I'm not trying to get burned for witchcraft while I'm sightseeing.
