So I'm sorry we never got around to reporting the most recent turns. The TLDR is that Saleucami's third ring border popped the very next turn when we moved in which (mostly) scuppered our move. I had planned for possible scenarios like Serdoa pillaging the iron road so we brought along three workers to road if necessary but I could not have guessed that the city would pop borders.
Nonetheless we had the backup plan to move in to fork Saleucami and Alderaan instead while moving in a secondary stack towards Alderaan with the medic GG (Sanctus Vox) and the newer C3 Morale GG (Aukuna). Serdoa decided to cat the smaller stack with two GGs and wiped it out, but at grave cost (Aukuna killed three units by herself before falling) and we were able to take Alderaan quite easily as well as clean up the units that killed our stack. We then moved the remaining units to take Corellia, which was lightly defended as Serdoa had packed most of the units in Saleucami.
After that we were able to get catapults up to Saleucami relatively soon which allowed us to take the city with minimal losses.
Rusten then agreed to peace with Lewwyn so we knew he was going to take Inpulsa back, so we went ahead and razed Malastare (after briefly debating leaving the city for Rusten to take) and were healing up and moving on Akiva and Aeos Prime when we were hit by the attack through SD's lands.
We were prepared for an attack by SD and by proxy we were somewhat prepared for Lewwyn's knight attack, but we were certainly not close to prepared for a combined attack. If it was just the knights we may have killed 12 or so out of the 23, and of course if we had some warning we would have built more units in the area and moved our units much differently.
Lewwyn also showed a two-galley boating force in the east at Beachhead, but we were (mostly) prepared for that and only had to dry whip a pikeman to deter it. We were working on a long-simmering Astronomy play with our iced Scientist and finally finished Paper (which I had forgotten is a new prerequisite for Galleons) shortly before the game ended and we did have a few galleons in the water just then. The plan was to possibly try to take Lewwyn's Moai city of Roadhog and the sister city of Mei and blockade all of Lewwyn's islands and otherwise threaten every coastal holding we found.
We were working on getting the National Epic in Ascent, which was the planned third phase of the city.
