Red Rider is one of the four horsemen of the apocalypse. He and his brothers' whereabouts are not known to the world Dream Port. They will only appear before beings that seek out the Aistear Creidimh to deliver warning, as wishing upon the Aistear Creidimh can disrupt stability of the world. Red Rider symbolizes war. He wields a trojan sword, symbolizing mass slaughter that would come after conquest. It is not known whether he is good or evil, as old folk tales only mention him as a warning.

Red Rider's name was taken from the biblical four horsemen of apocalypse. He is 201 cm tall and weighs 118 kg.
