Tarein is the name of one of seven Danethan soldiers stationed at Sakrah Outpost, the others being Antras, Casarte and Ceiden, as well as three unnamed soldiers. His name is mentioned briefly in Chapter XXX of Violet Sword Blade, "A Hostile Scout". During the chapter, Sakrah Outpost is attacked while Tarein is on duty as a lookout. He warns the other soldiers, but they are all killed nonetheless, with the exception of Ceiden, who is away cutting wood.
