City in the Clouds
Founded over half a millennia ago Sempyria was built off the back of several large gold deposits found near the peak of the Blackstone Mountains. Rather than construct their community at the base of the mountains, and climb them each time they wished to dig for gold, they built their city at the summit.
Due it its remote location and formidable defences Sempyria has never been sacked despite being laid siege to several times. The city’s vast gold and precious gem deposits make it an attractive prospect to any warlord wishing to fund his insurrection.
