From compartment 12-6, Arthur took out a staff with a beautiful silver metal head—resembling the crown of an octopus, filled with the early style of the Holy Empire.
After unscrewing the head of the staff, there was a storage compartment about 15 centimeters inside.
Arthur turned the staff upside down, and the contents inside slid into his palm.
A key!
The key was entirely made of copper, about 10 centimeters in length, adorned with streaks of green copper rust. The front end had a thick set of teeth while the handle was a hollowed-out semicircle, quite archaic in design.
The information about the key clearly appeared before Arthur—
[Name: Hercules' Key]
[Type: Key]
[Quality: Arcane]
[Attributes: None]
[Remarks: This is an exceptionally precious key, you can use it to unlock a laboratory of Hercules or his library, or even his collection room... In any case, you need to find them, then try each in turn.]
