In 5312 DE(2344 BC) a plague originating on Yasefe broke out in D'ni city. This caused widespread panic but was brought under control within days by the Guild of Healers. As a result of the plague, the Nehw'eril District was built away from the city proper to act as a buffer in case such things happened in future.
