Treasure or Torture?
Aleister couldn't decipher much of the verse written on the parchment because the words were confusing. And if he had to listen to his inner voice, then it looked like a child was babbling random things and ended up writing this.

When they went to the church and found that book named 'The Sea Creatures', it had no words in it. The pages were empty but the bookshelf where it was kept had these strange lines carved on it. And since the first time he read it, he knew that the words on the book would appear only by blood.
But the question remained… whose blood?
And it was not answered until Esme talked to him about her dream, where she transformed into something else. A half-human, half-fish, into a mermaid. Only then did he consider the possibility.
Even though the chances were low, it was the only possibility that he could see at the moment.
