I have been steadily assembling a rather large list of historical figures for whom we have no solid dates or information regarding their death, or whose bodies were never recovered. Why? Because we really know they were recruited by TimeWatch!
We'll start this regular feature off with a big one I'm sure most of you have considered:
Spartacus! Yes, that Spartacus; rebel gladiator who made a mockery of Rome's might, if only for a short while. See, although several sources state he was killed in the battle, it is also reported that his body was never found.
You know you want to play or encounter agent Spartacus, if only to step forward, all steely-eyed and shout, "I'm Spartacus!".
