If it makes you feel any better I would have moved sooner if Atlantis had attacked. Part of my hesitancy was the large army on my border not doing anything yet, and there was *no way* I'd sit around waiting for you two to get around to killing me with no Arco to distract you. I would have immediately attacked with whatever I had if you both were moving on Arco.
I've made a couple fairly big mistakes myself from sending in a bunch of non-lighting immune tartarians in to not giving gems to the guys scripted to drop in and rain of stones you to my previously mentioned flub where I just lost most of my good astral mages.
To be honest I was quite surprised at how fast Arco beat you back, it looked like he was sunk for sure with the amount of territories you took so fast.
But yeah, I feel like I've got my fangs sunk in and am tightening the coils now. Atlantis' capital is sieged and Caelum is rapidly bleeding to death.
ABANDON ALL HOPE. THE LEGION COMES AND THE ROTTING CORPSES ARE PILED HIGH. FALL TO YOUR KNEES AND BEG FOR A SWIFT DEATH.
