NHF – new heroes for Heroes V 3.1.

Here, on the first page, her name is Taveril, and in the mod, it's Taverille.

Taveril
Rumor has it that Taveril has a connection to fairies, who constantly accompany her everywhere. She herself jokingly says that she simply knows what the forest dwellers need. And indeed, Taveril's army always has many fairies.
And the secret is simple: during her campaigns, Taveril builds portable fairy houses, which are carried by ents. Even on the march, the fairies feel at home, and their numbers never cease to grow.

Specialty Description
At the beginning of each day, new fairies arrive in the hero's army, equal to the number of ents in the army.

Ents are not Zergs; they don't spawn anyone ;)
