The Dark Age explored the lives of a new group of Brothers and Sisters, struggling to cope in the new world left behind in the wake of the first trilogy.
The only one who can save them is Jack Churchill who, following the final battle with the dark god Balor has found himself lost in Bronze-age Britain This series begins with Jack waking up in The Second Battle of Mag Tuired, wandering about in a mist, he is beginning to forget who he is, and comes across a giant fighting with some Celtic warriors and ends up slaying it with his sword, earning the name 'Jack Giant Killer'.
The warriors convince the a village to take Jack in, who is miserable as he is losing his memories of Ruth and his life before, it is revealed that this is due to the spider embedded in his shoulder, which is eventually removed as it is apparently killing him slowly, whilst saving him four Iron Age Celts and Church end up becoming the first brothers and sisters of dragons.
Church eventually figures out someones killing off all brothers and sisters of dragons and begins to bring them back to the other world in preparation for a final battle.
When Niamh gives Church a chance of freedom he instead gifts it to Jerzy who races to a roof and tries to jump off and reveals he stole the lamp for the court of the final word and has a caraprix within his head.
In 1969 the libertarian offers Church a deal to be placed in a 'sleep like death' and locked in a casket in the otherworld forever, and in doing so Laura, Shavi and Ruth would not be killed in the present.
