I got a favorable secondary town, although guarded by up to 99 marksmen; I broke through via wasteland past up to 19 crusaders (the guys kept getting morale and eventually wrecked the ballista) and managed to capture the town by day 117. At home, dwellings 1-5 in Castle.
On the second, Gunnar with attack 12 and Expert Earth already, I reclaim resources, rushed a Dwarf Cottage on 20, placed birds in the secondary town, spotted an external dwelling of Rocs and Behemoths... But Ivan, citing a terrible layout, decides not to continue.
Thanks for the game!
