Kainnan, a settlement primarily inhabited by employees of Dessain Mining, existed as a city situated on Zerist. Zerist itself is a moon orbiting Obri, a gas giant found within the Tython system. This city was built at the foot of Sokar volcano to harness its thermal output as a source of power, which unfortunately meant the inhabitants lived with the constant danger of sporadic volcanic eruptions. To mitigate this risk, the Zerist government typically forecasted these eruptions and relocated the inhabitants during periods of volcanic activity.
