Professor Gracklebone chathead.png

Professor Gracklebone is a customer at the Arceuus House Library. He seeks certain texts within the library, and will ask the player to retrieve them. He will give players a book of arcane knowledge once a text is turned in, in addition to 1.5% favour.

Players who speak to him will learn that he teaches magic at the Tree Gnome Stronghold, and visited Great Kourend to learn its foreign magicks.
