Heroes of Might & Magic III: Horn of the Abyss

You can't call it an elven race because there is no elven dominance (only one unit).

Not one, but two: an elven archer and a pegasus rider (an elf is riding it).
All other units there are tamed forest creatures, except for the dwarves (forest dwarves), who form an alliance with the elves.
In addition, it is possible to create alternatives in the Rampart, in the form of a greater variety of elves.;)
