It’s good that at least “regeneration” was included.

It wasn’t included; it’s a preset.

Why not give the player that tiny chance to change history? I would value that one battle won by Lorenzo much more than all the other battles on the map.

Of course, if Lorenzo had won that battle, the history of Ashan would have changed, but I think not for the better. Biara wins the war against the rebels, summons demons with the help of the Griffin Heart, and then total, unconditional doom ensues. Who will save the world? Arantir is busy with the Messiah, Zehir has no one to tell about what is happening in the Empire, and even if he arrives there, he will see not a defeated Lorenzo and a handful of adepts with 5 landlords in tow, but a far more formidable foe. Faydaen is busy restoring Irollan. Railag is also chasing after the Messiah, as is Arantir. Gotai and Kujin? Maybe, but the chances are still diminishing.

And besides, all of this doesn’t fit into the history of the Unicorn Empire. ;)

The Horncrest siege option is the author’s idea.

This was conceived back in Nival, I just developed the idea. Here is a picture from the last mission of Lords of the North.
