Try to guess 20 first level administrative subdivision capitals (both in Kosovo and other countries) closest to Peja/Peć.
For practical reasons, I'll make some exceptions:
For Slovenia and Northern Macedonia, only largest city in every statistical region is included.
For Luxembourg, Liechtenstein, San Marino and Andorra, only country capital and largest municipality seat are included.
If some subdivision capitals are omitted but should be included, please let me know.
