They are heroes, writing chapters of civilization and painting historical pictures. Lead the world and leave indelible traces even through eternity. But they were rejected by heaven and earth and hated by all races. He is regarded as the most harmful person in the world and the mortal enemy of all living beings. Why is it so complicated? Or in their own words, they are just wanderers living in a foreign land. Hero? Disaster? Wanderer? Maybe they don't even know what it is? They are - time travelers.
