Bronze Worlds

Meanwhile, King Yama was trying to choose which of the 1500 worlds to destroy first.

She made a promise to herself that the Universe Expansion Pack would only have 500 worlds one it was complete. One gold world, where the winner would be decided, 10 silver worlds where they would compete for the crown, and 489 bronze worlds.

Her plan was to destroy one world every month, for 1000 months, in order to get down to the 500 worlds. That meant in roughly 85 years they would be into the bronze stage of the competition.
