Right, it's 8 am and I didn't sleep the night, so I'm blacking out and hoping that someone else picks up the cause of not going to Spain. Still, here's something I remembered, before I fall asleep.
Also, other than Rome or province, a third possibility exists - Marius fights Mithridates (note: I find it a bit funny that supposed "last breath of free Asia" as it was called in one of the updates, is actually only the First of Mithridatic wars. A rather long breath, that was), wins, but suffers casualties heavy enough that he requests the VI as reinforcements. There we would really have a chance to affect the civil war.
I guess Mithridates could also just straight up win against everyone and invade Greece again. Now that would be a funny way for history to go.
Here's two options of what could happen and where we would most probably get moved, should we stay with the Legion. In my opinion, both options are more interesting than going to Spain, and would indeed offer us plenty of opportunities for both glory and importance to the fate of Rome. Of course, like Telamon himself said, his post could be nothing but lies, but I do not think he would really tease us like so, if there wasn't some basis to his joke in the actual rolls.One of these possibilities is so disturbingly close to what the rolls have planned for y'all that I think you might be precognitive.
And no, obviously I'm not going to tell you which one.
And yes, obviously I might be lying.
