Landon Cadena is a newly trained squire who dreams of taking his place among these legendary defenders. When pale daemons swarm out from the encroaching dusk lands, Landon is thrust onto the frontlines of an apocalyptic war.

Landon 'Lan' Cadena begins as an ambitious young squire eager to prove himself against monstrous horrors. As he encounters ancient magic and deadly threats both inside and outside the Citadel, he grows into a formidable knight capable of wielding extraordinary power to protect mankind.

Across the trilogy, Landon's quest takes him from desperate frontier clashes to the ancient Citadel, a sanctuary filled with magi and living machines. As the threat of the void grows stronger, Landon must learn to control his expanding abilities to become a true greatknight. His journey culminates in a final battle against nephilim and daemons to secure humanity's ultimate survival.
