Due to a combination of factors, the current world will end at some point on October 30th.
When this happens the player with the most cash on hand will be crowned as Champion of Grey and will receive a free inter-planetary shuttle on the next world when/if the technology is invented there.
A new world, 'Lovelace', will start a few days after. This world will look similar but have a substantially different setup, particularly in terms of how the economy operates and how players can interact financially.
