- ↑ There are seven distinct letters present, but only the letters "M" and "E" are visible at the start of the name, while "N" is visible at the end. It may read Metatron, but too much of the word is obscured to be sure.
- ↑ It should be noted that aside from this bit of graffiti, Alessa makes no appearance nor is she mentioned further in the comic series.
- ↑ Two characters in the message are too obscured to be read, though it may read Pythagorean, referring to the Pythagorean Theorem, a math theory involving triangles. "72 Princes" may refer to the 72 demons named in the Lesser Key of Solomon, a book of magic.
- ↑ This is a reference to the Biblical tale of Jesus casting demons out of a man. The demons are noted for referring to themselves as "Legion, for we are many".
- ↑ These are all demons found in the Lesser Key of Solomon.
- ↑ The Compendium Maleficarum is a book on occult topics written by an Italian author, but it wasn't published until 1628.
