The problem with the legion is the problem that Despotic systems have always had: Every legate and Centurion with a gleam in his eye is after, if not that seat, some carved out niche. Assuming you can hold it, you've now inherited a greatly weakened Legion. You've got a few years of rebuilding to do at minimum.

Now, this is both a blessing and a curse. On one hand, you can introduce at least a few major reforms in the chaos and turmoil, your loyal core is likely to leap upon whatever you're offering while the less adaptive branches can be culled. On the down side, you have to keep the ravening hordes busy long enough to get your house in order. So what do you do?

Pitting them against each other is an obvious answer, you *might* get a leaner, meaner, more modern legion out of it. the risk is obvious however. You might *lose*.

So, assuming you're not at outright conflict with your former colleagues off the bat because you were hand-picked by the man himself before his unfortunate passing, the choice is obvious. Drive the legion against a new foe. Lead them into a war immediately. Have the ones you suspect to be a potential problem at the spear-tip. Either they die "gloriously" for the legion, serving as an example, or they live and you salute them and you can hopefully bring them over, showing you can bring them victories just as well as Caesar. Or simply arrange a tragic "accident". All strong possibilities.

If you lead them into an easy victory you've picked up some new loyalists and inclined them to listen to you. If you get into a prolonged fight, you're at least keeping them busy and the knives away from your back while you work on figuring out what you want to do with the legion as a whole. Of course, you could lose, but hopefully you picked a sensible enemy to fight.
