Well, unfortunately this exact artifact isn't present in the game...
Yes, I'm serious, as you are currently becoming too strong. Seeing your Tartarian Factory (TM) at full power isn't exactly healthy, if you know what I mean...
And as I see it's soon to be ready, so I would prefer to have means to stop it if nobody else would.
It was canceled the turn after your attack on R'lyeh capital - as can probably be seen from post date.
So, according to our initial agreement it expires after 4 more turns. After that, it's probably a war time.
My sincere apologies to Marverni, of course, but currently Sauromatia becomes much greater threat than Abyssia - and the latter has difficulties enough defending itself against Tien Chi & Yomi afaik, so you can take an offensive here. I am also still able to give you items at discount prices.
