Ancient Demon's Spell Book

Ancient Demon's Spell Book is a book granted or bestowed by an unnamed Ancient Demon that visited Hoaqin in his sleep.

History
One night, an Ancient Demon came to visit young Hoaqin in his sleep. The Ancient Demon then told Hoaqin to deceive his 4 siblings Vicente, David, Anna, Albelda and offer their souls to the Demon itself. When Hoaqin woke up, there was a spell right in front of him. His thirst for power lead Hoaqin to read the spell as if he was bewitched.

Spells List

 * Spell of Soul-eating: the demon gave Hoaqin this Spell as a way to become stronger by devouring the souls of his siblings to become one god-like entity.
 * Mysterious Sigil: this sigil is an inscribed or painted symbol that was used by White to undo the effect of Spell of Soul-eating. This sigil can also backfired at Hoaqin, because even if one of them (Hoaqin or his siblings' souls) mingles into the sigil, White can't be resurrected.
