Legio Quinquaginta: stay tuned

[richsc]

In what is most likely the most momentous Roman military discovery ever, I will shortly reveal the true, historical and factual source of those nagging and persistently awful reconstructions plaguing our world: to wit, Legio Quinquaginta. You have never heard of it because it was periodically subject to damnatio memoriae, all of them. But Leg L was so consistently practical as a repository for everything awful in the real army that it was continually reconstituted.

Normal Legions have an iron hand as their symbol, fingers & thumb up and pointing to Jupiter.
Legio L had a unique manus/hand symbol. It will be revealed soon (unless you can guess it).
