Cataloger Jamillah informed me that a murder has been committed in the once tranquil halls of the Library of Erudin. The victim is one of the eight Scholar Primarchs who oversee all research conducted in the library. I've agreed to deduce the identity of the killer by finding clues within the library. To be certain who the murderer is, I'll need to ascertain the room where the murder took place as well as the weapon that was used.
