If someone is run over, their name resolves Yes. If they aren't run over, their name resolves No.

Each name has been randomly paired with another name, and presented as a poll. These polls will resolve N/A, and all mana you spend on them will be returned to you. But at market close, I will tally everyone who holds Yes and No shares in each poll and use this to determine who is run over by the Time Trolley. The individual names then resolve Yes or No accordingly.

The Fiction:

You are the conductors of the Time Trolley. There's been a terrible accident, and you've been marooned in a distant timeline. 

The only way home is via a branching series of Time Tracks through nearby timelines. Unfortunately, each Time Track necessarily runs right through a historically significant figure at a historically significant time. If the trolley runs over someone, they suddenly die of an aneurysm and that timeline has to deal with the consequences.

As the Time Trolley conductors, you must choose which tracks to take and therefore which historical figures will survive in those timelines.

The Mechanics:

In this market, you can submit significant historical figures and the moment they will die if run over. Limit of 4 submissions per user.

When I think we have enough options, I will randomize a time of day to close this market to submissions and then randomly pair up the submissions. I will then create a poll for each pairing, asking who the trolley should hit. Exact randomization and poll format is TBD, but will be announced in advance.

I will make only small trades in this market, to show support for submissions but keep myself impartial. This is an experimental format, and I may make minor adjustments to the rules if anyone has good suggestions.

You are encouraged to argue the merits of running over each person or not in the comments, to try to win support for your bets.
