Question about the map "Longest Journey".

Here, you need to kill Kalida and all the blue heroes because you need to move on, and everything here should belong to you. Of course, you can’t defeat Kalida head-on. I remember blocking one of the blue heroes at sea (either during the first or second playthrough, I don’t remember). The main thing here is to act quickly enough to prevent the enemy from getting the rusty dragons (this quest assumes that we can take them ourselves if we want), otherwise, the enemy becomes too strong. The same applies to the brown faction: on his territory, there is a hut with a quest that gives 46 crystal dragons. If he manages to get them, it will be very difficult for you.
By the way, there is an easier version of this map called "Longest Journey TE". As far as I know, there are 2 differences from the original: a funeral pyre in the starting zone at cell 30,3 and the Sword of Justice at cell 11,71 (both are in a dungeon).
