Helmrick has been positioned as the ‘antagonist’ in this story, but it is clear that he is lonely and desperate rather than evil... The vampire has not 'kidnapped' Oliver... rather he turned him into a vampire to save his life after the wizard accidentally died whilst investigating 'Ira', the vampiric deity who has taken refuge in the castle. Despite being the 'lord of the manor', he actually holds no power over the people who reside with him as they all worship the deity Ira...or other parties (to be discussed shortly).

 He was once desperate to be a Cleric, but was forbidden from doing so due to his family lineage (his father is the true Vampire Count in a foreign land and he would never approve of his bastard son joining the vampire cleric schools...)...Helmrick is still intensely devout to Ira, even in his ineligibility and does what she says without any verbal questions (though he tortures himself with the implications of her asks, it is implied his faith is a 'crutch' to prove he is a good person). 

His only possible 'ally' is a servant called 'Driscol' a man who has raised him from childhood... however, it is clear that Driscol is obsessed with Helmrick's father 'Angelus'... The vampire noble Count from aboard. Despite being a bastard child to Angelus, Driscol has raised Helmrick to be his father's physical clone, his hair, clothes, spoken manner, style and appearance are all exactly the same...making Helmrick feel wretched... he is a poor replacement for his father and unable to be a cleric.  

In truth, Helmrick simply wants to have friends and people who will pity him,  he sees the Fae rescue party approaching as a chance to negotiate for his, Oliver and Sirius' freedom (he is very cautious, as he has only ever been treated badly by everyone he knows), as he is cursed to remain in the castle until a member of Fae Royalty sets him free. He is 30 years old, but as a vampire, he is somewhat ageless. He has been trapped for over 20 years, it is understandable therefore, that Helmrick has trust issues. He also has torturously strong ESP, meaning he is able to sense that everyone in the castle dislikes him...he can control others, but will only do it at Ira's request...as he himself, sees friendships and allies who are being controlled mentally as puppets and has no interest in such a friendship.   

Helmrick is melancholy, tortured, stiff and pensive...…he is almost hopeless that even if he does have the opportunity to escape...Ira will forbid it...and thus he would have to stay...and even if she did allow him to leave, he may be misunderstood by all living creatures. It is unspoken, but he hopes that he can strike up a friendship with Oliver, and perhaps the wizard can help him adjust to life outside the castle....he has given Oliver a second chance as a vampiric Cleric, but Oliver has become enthralled with Ira...and Helmrick is heart broken...as he is once again alone.  

If given the chance to blossom, Helmrick would be the Virtuosos personality type, he wants to learn how to do things for himself, instead of relying on others, but his current situation makes this impossible. Helmrick can be very passionate about things he cares about, but has been stifled by what is ‘appropriate’ for his social class. https://www.16personalities.com/istp-personality

Helmrick would have a well-spoken educated accent (WE WILL CONSIDER EUROPEAN/ENGLISH AND OTHER BRITISH ACCENTS ALSO), he would speak with fluency, his voice is smooth, deep and bassy... it would be alluring and command presence...despite his inner struggle, he will always present himself as a strong and confident person when people 'outside' of the castle inhabitants are around...he is excellent at 'putting on a show', and Ira counts on this. The main conflict of this tale is that Helmrick is not a bad person, yet, he is doomed to die.

Helmrick's outcomes are sadly tragic, he will die in the vast majority of endings, but his limited emotional range will break in certain situations (he will break down into tears and scream with grief in certain scenarios).
