Which series in the Heroes Chronicles did you like the most?

Hey everyone, I just finished playing Icefang and I have some questions about the plot. 1. As I understand it, Heroes 4 started with the convergence of Armageddon's Blade and Icefang? Was it Jelu and Tarnum who clashed together? And also, at the end of "Icefang," it says that Kijda (the barbarian woman) stole Icefang, while Armageddon's Blade is with Tarnum. 2. Has Icefang never clashed with Armageddon's Blade before? I mean, in other parts or somewhere else. I read somewhere that "Armageddon happened because the blades clashed, and the ancestors didn't like it. They sent Tarnum to save the world." Thanks in advance!
