Oh great Po Ngbe, our scholars have made a shocking discovery, the concept of number representing pure nothingness, describing the level of sympathy Jaguar feels to its prey. In the hurry, they called it 'zero' and ask for your guidance.
a) This concept is too dangerous. We must hide it from the world and kill those "scholars", before Gods will punish us! (Mathematics is lost, it would be good to remove all scientist points generated so far, but they are none
Ok, it triggers "Scholars' hunt" spawning 3 barbarian Great Scientists, you lose faith per turn until those units are killed. )
b) I give 'zero' cares to it. (you no longer decides about tech research queue)
c) Oh, that's interesting. Let's divide something by it! (80% nothing happens, 5% your people are enlightmented +300 faith, 15% your empire collapse leaving you with one last city with one population and no buildings... you got the concept)
