Awakening of Evil

Hello everyone! Huge thanks to the author for this wonderful campaign. I almost finished 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, then 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... And now, the question: I accidentally (well, not exactly accidentally, they all started fighting and killing each other) killed him... will I be penalized for this 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 as great as this one. With respect to the author, Tiard Tinn.
