Thank you for the interesting map; I completed it in hero mode, playing as the Dark Elves, in just over two months. :smile03:
If you have any doubts, I can upload screenshots and the final cutscene.
Moreover, during the entire battle, I never ran away from enemies; I played as Rylag, and he cannot be hired in a tavern if you flee or surrender.
Big respect to the author – I had three interesting evenings playing it! :)

Today, I'll try playing it as the Sylvan faction; I'll let you know how it goes.
