Kala'din
once a sister-city to Kala'uun, Kala'din was the site of an ancient ryll mine. After its hidden location was sold to the spcie merchant Brophys by a Twi'lek named Kroh'dalla, Brophys enslaved Kroh'dalla and forced him to mine ryll. After incredible amounts of ryll were extracted from the city in virtually no time, Kala'din collapsed in upon itself, killing Brophys, Kroh'dalla, and everyone who lived there. Kala'din ceased to exist, and became the subject of a Twi'leki fable whose moral was, "Once a secret is revealed, it spreads until the truth above is destroyed."
