His poisonous elixir

Eleanor Judith, from the noble house of Judith, never thought of love, for her it was a trivial matter, sure, she had a few scandals here and there but they by no means were true and were also suppressed due to her family's name and money. Despite what others might think she was not a spoiled little girl who does not the ways of the world, she was quite a woman even at early age of 13 when her mother died.
Charles Spencer, from the noble house of Spencer, despised the feeling or even the word love yet yearned for it, he despised for how it made him weak from within yet loved how it made him feel warm. Obviously he had read about love time to time, he has read how everyone describes it is a warm bonfire on a cold winter night or maybe sometimes the fireworks in the sky that he has seen in the carnivals but doesn't that sound too silly, in both these cases you are at some point bound to get burn and the fire might just burn the two lovers basking in each other's warmth.
William Tudor, from the noble house Tudor, was quite the golden child, has the good looks, has the money, has the name, has the support and definitely has his father's approval -no- well we'll get to it at some point, but anyways moving on, to everyone he is the person who gets everything he wants. He is quite the boy whose head is in the cloud, But don't they say, the cute ones keep the most secrets.
Isabella Leonor, from the house of Leonor, was a bubbly person with charismatic looks, her antics were well known to the nobles. She was the person to go-to if have problem, many even thought she could become a well-known therapist but my, my therapist does not really go with the name of Leonor. Leonor is a house of secrets they are known to be skilled swords.
