And here it is!!! :D (emerald head)
Dragons with horns are usually depicted – it’s strange that in Heroes 5, neither the Black nor the Green faction has them.
They should live in harmony with nature, so it would be possible to make buildings from stone and use wood to a minimum, for example. If we don’t count the deer head on the High Druid and Ranger, and the wolf head on the Elder Druid, then otherwise, the elves are more or less keeping within reasonable limits.
