Professor Imblewyn

Professor Imblewyn is a gnome wizard found in the Magic Guild. When talking to him, he tells you that gnomes are interested in everything. He can be a hard order in Gnome Restaurant. One of his rewards for delivering food to him are soul runes.

If you have completed A tail of two cats after the professor says:" We have a saying, 'curiosity killed the cat'. But cats aren't clever enough to understand what they find. Gnomes are." Your character will reply: "Hey! Some of my best friends are cats."

He also appears to be weilding some sort of a red Staff of Guthix.
