Belinda Benson is the heroine of Dark Matter: The Secret Revealed. She is an 18-year old immortal healer who has lived since the sixth century. She is slim, with short cropped blonde hair and bright blue eyes. Belinda can be emotionally intense and expresses her feelings easily and abundantly. She has a direct manner and does not mince words. Her beauty emanates from her fierce determination to follow her path in the face of adversity and great loss. Her loyalty to those who she loves is an immense strength that gives her the will to persist and never surrender to despair. She is dedicated to serving a greater purpose in her life and believes in the transformative power of true love.
Damien Francis Garant is a very mature mortal of 18 years who has a strong penchant for science and dreams of one day becoming a physicist or biomedical scientist. He is a very compassionate human being, a very good son and a sweet and adoring boyfriend who captures Belinda's heart. Belinda views Damien as an old soul who has a great deal of wisdom to impart. His journey through the novel demonstrates his resilience and ability to think outside the box. Like Belinda, he has a strong will and is determined to figure things out for himself. He has a healthy ego, and at six foot, with magnificent blue eyes and chestnut curls, he is a handsome man whose heart belongs to Belinda.
Lady Cerridwen is Belinda of the past when she was a mortal High Priestess of the Isle of the Mists. She is a progressive leader dedicated to finding common ground between the beliefs of her people and the emerging Christian religion being adopted by the Britons of the mainland. She is deeply committed to a life of service and struggles with her growing love for Sir Gareth, a knight held in high esteem by King William and his court. She worries about the impact of their relationshiop on her responsibilities as High Priestess and whether marriage can be an option for a High Priestess. She is very kind and generous and graciously welcomes Belinda into her mind and her body upon her future self's arrival. Cerridwen, like her future self, is beautiful with long and thick strawberry blonde hair, a generous bosom and a presence that commands respect from even the most powerful in the land..
Sir Gareth is a highly-regarded knight who serves in the Court of King William in the sixth century. He is an immortal dedicated to using his immortal powers to build a better world. He falls in love with the Lady Cerridwen during the Winter Solstice Celebration on the Isle of the Mists, and together they begin to build an important bridge between their two worlds even in the face of Sir Gareth's brother, Mordecai, who mounts attacks against the Lady Cerridwen. Sir Gareth is a sensitive and compassionate immortal whose wisdom and strength of character inspire the Lady Cerridwen to face her heart and conquer her greatest fears.
Michael is an Old Immortal who has a great deal of power and immortal gifts. He and three other Old Immortals formed the Group of World Servers in the sixth century, and Michael was the Inaugural Supreme Council of the Group. He is also Belinda's protector and tutor having brought her under his wing many centuries ago. Michael is deeply committed to the healing mission of the Group and lives his life by its Code until Belinda's life is thrown into turmoil when Damien suddenly falls deathly ill. As he helps Belinda find her power and her true path as an immortal, he must somehow reconcile his commitment and loyalty to the Group and its Code with what he must do to protect Belinda, who he has loved deeply for many centuries.
Mordecai is Sir Gareth's immortal brother. He is a very powerful and evil immortal who kills other immortals so that he may acquire their immortality. Unlike his brother, Mordecai is self-centred, cruel and desperate for power. He also serves in King William's Court, but focuses his energy on acquiring greater control over the mortal world and his immortal bretheren. He is threatened by his brother's relationship with the Lady Cerridwen and seeks to destroy their bond through a myriad of attempts on Lady Cerridwen's life. Mordecai has one saving grace--his love for the Lady Mariam, Lady Cerridwen's mother, who is the only thing that stands in the way of Mordecai becoming a complete monster.
Thomas Hector McTeague is a tall immortal with a generous mid-section, thick and wavy brown hair and bright green eyes. Michael sought him out early in the seventh century realizing that he could not always be at Belinda's side. He needed someone he could count on to stay with her and keep her safe during his absences. Thomas is a loner and has shunned immortal society for centuries. Although he is a member of the Group, he is not one of their favourite sons. He is a venture immortal, originally from Scotland, who takes extreme physical risks that the Group frowns upon because he hazards his true identify for no apparent reason. If Michael or Belinda had to bet on someone to pull off a miracle in extreme physical conditions; however, it would be Thomas.
