Summon forth your genie of the lamp. Not the actual being of legend so cannot grant wishes─unless your wish is to be carried somewhere.
In the region of Corvos, there exists a legend of a lamp-dwelling spirit that grants wishes to its master. As this particular entity is an imitation later brought forth by a sorcerer, it is far from the omnipotent being described in tales, but in accordance with its creator's design, it will dutifully carry you wherever you wish to go.
