The Rue Guardian is the Casterwill family elder over curses and secrets. As the head of his house, he leads the other four Rue Guardians.
When the Blue Star was activated, the Rue Guardian and his house were among the representatives of the Casterwill family who met at the Fortress of Iron Will. Like Focauld Casterwill, he opposed the presence of Lok Lambert for not being a member of the family and voted against open confrontation with the Blood Spiral.
During the Blood Spiral's assault on the Fortress of Iron Will, the Rue Guardian and his order of four worked with Focauld Casterwill an ancient incantation, simultaneously invoking Coralgolem, Feyone, and Icarus Amulets within the stronghold.
The Rue Guardian leads a mysterious and mostly silent order. Though Lok Lambert perceived him as potentially dark, Sophie Casterwill presumed that, by his familial association, he had good intentions.
The Rue Guardian holds the secret knowledge of the Fortress of Iron Will and the Amulets hidden within. Together with the rest of his house, the Rue Guardians are capable of summoning an army of Titans to their aid.
