Weak start, only 4 archers and they aren't built, but there are two prisons nearby; freed two level 5 heroes (both mages). On the first one I leveled Valeska, as the path to the swamp secondary was blocked by 19 cows guarding the artifact. On the second one I switched to a mage who has logistics. On the third, I placed the first Dragon Utopia and angels; on the second, three more Dragon Utopias. It's hard to take them with a mage, all troops are wiped out, but I managed to gather plenty of wyverns
Iona level 21 18 18 15 22 (330 mana, expert air, tactics, armor etc., golden bow, +1 speed) strike stack of 32 monk wyverns and some odds and ends, a couple of archangels etc.
Thanks for the game
