The Arms of Robert Brian Heinen - The Armorial Register.

The field of Azure (blue), was chosen to symbolise loyalty, truth, and perseverance, the Gules (red) fess divides the shield, representing strength and military fortitude. The three unicorn heads erased Argent (silver unicorn heads, torn from the body) symbolise purity, courage, and untamed spirit. Unicorns are often associated with wisdom and virtue, and their placement in chief suggests that these qualities are of paramount importance.

The key Argent represents guardianship, knowledge, and access to secrets. The hound passant Argent (a walking silver hunting dog) represents loyalty, vigilance, and service. Hounds are often used to indicate steadfastness and keen instinct.

The mantling is Gules and Azure doubled Argent (red and blue with white lining), reflecting both martial prowess (Gules for strength and courage) and steadfast loyalty (Azure for truth and perseverance). The artistic flourishes of the mantling, inspired by medieval battle coverings, enhance the historical depth of the design.

This achievement was designed to convey a person or lineage that values wisdom, strength, vigilance, and nobility of character. The combination of the unicorn (virtue), the key (guardianship), and the hound (loyalty) paints a picture of an individual or family that is both fiercely independent yet deeply devoted to duty and trust. The Azure and Gules mantling further emphasizes a balanced blend of courage and loyalty.
