We've discovered something truly unacceptable has happened as a result of Professor Parallax's brief visit to Ethiopia in 850 BCE. The discovery of coffee has been set back by centuries, espresso martinis have never been invented, and brunch is in serious danger of becoming a very lacklustre experience indeed.

Our research has shown that the discovery of coffee hinges on one particular goatherd observing the effect on one particular goat after it eats a particular cluster of caffeinated berries. And the Professor's unfortunate sneeze spooked that very goat — meaning none of this has happened.

We need your help. We've hacked together a Temporal Simulator that lets you experiment with small interventions and see if you can find a way out of this pickle. Head to Committee Room 3 to gain access.

If you can put things back on track and show brunch is restored to the scientist in that room, you're more than worthy of a Convergence object. Quick — brunch is at stake!
