The scenario “Knight from the Order.”

Guys, how do you recruit them? I can't seem to do it.

The lists are mentioned above, indicating how many troops to bring to the keyholders...
You can discard the excess troops in the garrisons of nearby mines,
take the key, and then recruit the units again. :D
The mission is simple, but it's quite long; it took me 6 months and 1 week.
I saved once, before attacking the "Dragon Utopia."
As a result, I got so many artifacts that I looked like a Christmas tree :D
I wish it were that easy to get artifacts in the campaigns... I filled all the slots and the entire
reserve.
