I can't recall right away. I think there are two: one near the mentor, and the other on the eastern island.
Yes, there are two.

Thank you very much; I spent about 30 minutes studying the open map and was in doubt. =[br][/br]

Finally, I completed it. More time was spent running back and forth, and those lake creatures are such a nuisance, they wander everywhere. I didn't choose to eliminate them as a class because the dwarves are even more annoying.

The lack of magic skills when leveling up heroes was compensated for by "Fallen Knight" and "Twilight." With chaos and summoning on this map, you can survive until the 2nd month, but there's no point after that.

ANOTHER question, because I can't figure something out.

Does the effect of Varen's ability - Thunderclap on all troops - depend on the soldiers' luck, or is it a different matter? And is the soldiers' luck "just given" to Varen at the beginning?

If it doesn't depend on it, then it's better to take something else, perhaps Logistics and Keen Mind.
