Completely disappeared without a trace. And deserters, who should have been brought back from previous installments of Heroes.

1. Humans - Demons. Based on the strongest creatures, it seems to represent the conflict between good and evil (Angels and Devil). 2. Elves and Dark Elves - Light and Darkness. 3. Undead and Mages (a clash of powerful magic). 4. Dwarves and Barbarians (first, magic versus strength; second, they are left without a pair). This is purely a subjective opinion.
