Mermaid Princess Amelia – Best Mermaid Book Series For Teenagers

Dorian Calidus is Dominic’s full brother and Samantha’s other stepbrother. Like Dominic, he is described as corrupt, and he is thrown into the pit alongside his brother and his adopted siblings. The newspaper clipping that Amelia reads confirms his imprisonment, but he is never rescued; the protagonists focus on freeing Augustus and Silas, leaving Dorian and Dominic to their fate. He has no personality traits beyond his shared corruption, serving as a paired antagonist who, together with Dominic, represents the venal, power‑hungry faction of the Atlantean court.
