Goblin outriders — sometimes jokingly referred to as "goblin knights" by other humanoids — are goblins that have formed unique bonds with wolves and similar beasts, such as dire wolves and worgs. In battle, they act as scouts, though some hobgoblin warlords use them as harrying troops and send them into battle with nets to restrain opponents.
