In Sibiu, Transylvania, Romania.
Btw, In Romanian Transylvania is called Ardeal although Transilvania (with "i") is also used. In Hungarian (some parts of it are predominantly Hungarian-speaking) it is Erdély (pronounced [ɛrdeːj]). In German (unfortunately the majority of Germans are gone from the region) it is Siebenbürgen (seven fortresses). And in Turkish it is Erdelistan or Erdel.
Yes, this is how write my posts here, I often have no idea what it is going to be about when I start. Here I started with a picture of some dude flashing his underwear and ended with how they call Transylvania in Turkish. Makes sense. If anyone needs tips on how to improve the flow in say your fanfic, I have a lot to give obviously and will be happy to help.
