Does Nila start without knowledge on this map? I only noticed that it was edited by the author based on Sylvia; she starts with summoning a boat.
Orrin also discarded the Cloak of Renunciation (one of the most interesting aspects of the map; I never figured out why he did it), or did he manage to leave the red player without castles for 7 days?
Based on what Frifix wrote under my comment on HP, I conclude that:
a) the author intended for the player to collect liches to win. After completing the map, I realized how they could be gathered faster than by catching the "Monster of the Month." We surrender as many of our castles as possible to the computer; it buys troops; we farm liches from it;
b) the author doesn't realize that the Dimension Door is not needed to complete the map. Accordingly, a number of quests in the Scroll of Destiny zone and beyond are unnecessary.

In terms of managing turns through a large number of heroes, I only used more heroes per game day in Where the Beauty. There, up to 30 heroes could be used in a single day.

P.S. I would be grateful if someone could suggest where I can upload the file so that it remains available for a reasonable amount of time.
