The veil is lifted.

I think I'll wait for the corrected version so that nothing spoils the walkthrough.

Two more:

1) During the Zephyr cutscene (the first one), Lorenzo doesn't have half of his animations, and he just freezes.
2) After completing the "hellish" teleport, where there is only one hero, the next region's trigger freezes with the error "hero Orlando is not on the map".

Okay, well, I think I finished it.

Duncan ran around the map, collecting resources; Frida fought. I leveled up Frida in defense, machines, and something else good. She fought quite well.
I got tired of capturing mines. In the end, I gave up on them, sometimes killing the guards if a hero was nearby.
Weak towns, strong neutrals. Perhaps due to the numerous script failures, but the enemy's towns were extremely weak. The heroes also had practically no army.
Among the interesting battles, it is worth writing separately about the battle with the mage and about Lorenzo, the monastery guard. I struggled with the latter, as I was sure that the summoned units would disappear, and I kicked the remnants of the regular army until his units ate me and succubi shot me.
I killed the mage on the tenth try. He needs to be nerfed. Only Frida's special ability helped - divine retribution left him without archers. Otherwise, I wouldn't have made it - you can't buy archers in the towns yet...
The map is a bit confusing - I was sure I wouldn't find the Monastery, and I even got scared.
Why spend so much effort on Warriors who cut down trees in the South? Even the Mage's Outpost is located there. I didn't find anything interesting.
I couldn't complete the last battle - the Orange Castle was at zero. Lorenzo with a good armada was also floating somewhere, but I didn't kill him.

In general, it's a very beautiful, well-made map, with interesting scripted functions that I don't have access to yet, a good plot, and old-school Heroes of Haven.

Thank you very much for the enjoyable evening! I will play it again on Veteran in the future, I hope.

Sincerely,
Best wishes,
Good luck with fixing the bugs! Thank you for the remaining days until the execution of the Monk in the ~~~ panel!
Thank you again.
