For the fifth installment, I suggest the following general ideas:
1 - Tell the story of the unification of the Swamp creatures, the Underworld dwellers, and a part of the Elves into the Dark Elves.
2 - Tell the story of the creation of the Human kingdom by Robert Ironfist and his brother Lysander.
3 - Tell the story of the heroes returning to Enroth from Axeoth.
4 - Don't forget about Sandro!
1) I can tell everyone who doesn't know the main events of the 5th installment's campaign in sequence.
2) I can create a storyline for a campaign set before the appearance of the Seventh Dragon when the 5th installment's editor is released. + create maps for it.
The fact is that there are many storylines in the 5th installment's campaign that can be beautifully connected with the revival, without any contradictions. I really hope you don't try to force the Elves and unite them with their enemies, the Swamp creatures, because it looks very artificial and contradicts the history. And by the way, there are mentions of Sandro in the 5th installment, as I already said.
The revival should be the threads that connect two pieces of canvas, and not a new fabric, even if it is silk!
Lеха, as a historian, you should know that everyone who writes history tries to see it the way they want, which is why history is often distorted to the point of being unrecognizable... I hope that you are learning from the mistakes of the past and will not become like such historians!
I really hope that this project will be large-scale, beautiful, logical, and True (not contradicting any of the parts).
With great respect for the project and its author, AlexeyPank, Supreme
