It all turned out fairly easily, despite the fact that Ivor only brought 3 archers, the 2nd level wasn't built, and no one else seemed to bring any more archers. The opponent had 2 external dwellings of monks.
After a few days, I broke through to the mud and a box, and along with the stat boosters, 5 Centaurs quickly gave me development. On the first day, wood at the Citadel, on the second day, horses.
Thanks for the game.
