Awakening of Evil

Hello everyone! Huge thanks to the author for this wonderful campaign. I almost completed the first map. Out of habit, I started on the "Hero" difficulty, but after looking around, I wisely lowered it to "Veteran." It didn't help much, and while wiping away the blood, I didn't get discouraged. I made a loop around the map, searching for the red tent, and on the second loop, I gathered and upgraded everyone I could find, and then I went around beating up everyone (well, almost everyone) I encountered. Everyone who wasn't a dark elf got it, and then I got beaten up by the strange green elf, Ossir. He was strange because, as far as I understand, he brought half of Erathia with him... Now, the question is, I accidentally killed him (well, not exactly accidentally, they all started fighting among themselves and killing each other). Will this have any consequences on the map? Is he connected to anything? Any plot points or scripts? By the way, I killed him fairly easily in 3 minutes, without cheats, using only "Berserk," Wall of Swords, and 30 minutes to kill 26k unicorns that were disgustingly resistant to magic. I'll continue tomorrow; I hope the next maps will be just as great as this one. With respect to the author, Tiard Tinn.
