I got a bit lost and ended up in a treasure zone instead of the center, but there I found several Dragon Fly Hives + artifacts + a Dragon Utopia. On the third week, Gurney runs off to take a Conservatory, while Nagash finishes off 500 skeletons and with 24 ducks takes the max Dragon Utopia. They gave many artifacts for combat stats. And on day 137, birds are built in both castles. On day 141, I take the Griffin Conservatory #2, buy out all the resources, and see Kirya charging at me. He has only 80 Grands, 7 Angels, 14 Horses, and Wood. I have 11 birds, 2 Angels, psychos, 500 skeletons + 20 Liches (obtained from a quest). Plus, Gurney's combat stats are higher by 20+!! After a volley from the Liches, which took down 20 Grands and a few units of Wood, the opponent surrenders!
Thanks for the game!
