How it works
After this market closes, I will ask @FairlyRandom to generate a random number M among 1 to 100 in the comments. The Mth unique trader of this market wins 300 mana from the lottery prize pool, if such a trader exists. Otherwise, the lottery falls through till next time.
For free play, make a trade with 1 mana and sell it. A galactic year is about 2.5*10^x Earth years -- it counts the total time our Solar System takes to rotate around the center of our galaxy.
This market will resolve to x%. The average magnetic field strength in the diffuse interstellar medium is on the order of 10^-x Gauss.
