Heroes of Might & Magic III: Horn of the Abyss

Inferno is not a race of demons, but of Krigans (aliens), to which demons, devils, spawn of evil, and imps belong.

I called it a race of demons in contrast to the "race of dwarves."

There is already a race of elves – Fortress.

It cannot be called a race of elves because there is no dominance of elves (only one unit).
