The Empire is whole again, but at what cost?

With a final charge of the Empire's knights, led by the Mad Count of Averland, the last pieces of lost territory were retaken from the Kislevite upstarts. However, beyond a thin veil of lies and formalities, the Empire of Man is now ruled by a single merchant, the cutthroat Director of Marienburg. Once merely the richest man in the world, now a man of absolute power, who has half as many land ships crossing the Empire's provinces in his name, as he has convoys sailing all around the world, ever diligently working to make him even wealthier with no end in sight.

Very entertaining run and probably my favourite faction mod next to Araby. For about 40 turns it was rather tight, with the last 15 mostly being auto-resolving my way to the long campaign victory.
I would love some suggestions for the next campaign, anything goes except Empire, Cathay, Kislev and Norsca.
