Hadrian Rakethorn

Doctor Hadrian Rakethorn is an English scientist who is assigned by Queen Albia to be Agatha's laboratory assistant while the latter woman is living and working in Albia's submerged kingdom. At least officially; his true purpose is to help lure Agatha and Co. into becoming permanent inhabitants in Albia's metaphorical Garden. He is chosen for this duty because he is officially catagorized as Clever, Dashing, Competent and Patient.

That said, it is not yet entirely clear how aware he is of this second mission; as seen in the page image, when he first meets Agatha, Zeetha and Violetta, he is.. um.. "dressed" to (successfully) impress, claiming that his waterlogged state is the result of an accident in another lab. Whether this is the truth remains to be seen.

Before being pointed towards Agatha, he is reported to have been assigned to work in "the Central Armory" after an unfortunate incident involving alchemical engines.
