Thuncryft

Thuncryft, an abandoned human port city the gnomes discovered after crashing into Respice. They then rebuilt their ship from scavenged parts from the city. They didn't explore the city more than they had to; once they got their fortress up and flying there was no need to. They designated an area in the city for ground to ship transport and ferrying of goods and blocked off the rest for fear of what might lie in the city depths.
