The goblins' talent in animal training far exceeded Gaven's expectations, especially those hobgoblins recruited from the Giant Plains, who have a long history of animal training themselves.
Not only do they use cattle and horses for transport, they even train crows to exchange information.
Training ferocious wolves to help guard prisoners, protect goblin camps, and selecting the strong ones as warwolf mounts goes without saying, it's well known.
Some Hobgoblin Tribes even train fierce carnivorous apes as their battle beasts.
Initially, Gaven dispatched some fae race druids to assist in taming those giant wild animals, and once the hobgoblins' abilities in this area were unearthed, they gradually withdrew.
