Enemy

Creatures that meet and battle each other tend to become enemies of each other. There is no known effect if a certain character has become the enemy of another character or of an empire. Most often, the worlds are so big, that the two creatures either don't live long enough to meet each other again, or one of them get killed before having time to express their enmity.

In Adventure mode, attacking a member of a group in the view of other members results in the exiling of that creature from the sites of that group.
