"Creatures from Another World"

A mysterious book that used to belong to Helcephein and Ilza's mother. It is unclear when, where, and how she obtained it, especially considering the fact that knowledge of "another world" was not very common during her time. This also raises the question of who wrote the book, but so far no traces of any potential author have been found. The book is written in Latin, and there seems to be only one copy of it.

The book mainly describes strange and fantastical but occasionally horrifying creatures that hail from an equally fantastical and horrifying world. The greatest of these creatures seem to be Dragons- flying, reptilian creatures with an intellect that far outshines most other beings and destructive power that puts practically all super-weapons to shame. The book mentions that these creatures possess a strong sense of justice as the main purpose of their existence seems to be to combat evil in their world(and prevent it from seeping into other worlds) and to maintain order, and as such they will only be allies to other allies of justice. Still, some of them are rather capricious and are prone to toying with "lesser" beings- there was apparently an incident in which a Dragon razed an entire country to the ground solely because the urge struck it.

Since the death of Helcephein and Ilza's mother, the book has remained with their father, Beelzebub.
