Transmigration

From Tardis Wiki, the free Doctor Who reference

Transmigration was the skill of defying the laws of pure science and pulling objects out of thin air. (TV: The Ambassadors of Death)

It was practiced by students at the Academy, despite warnings from their instructors that it misused the Rassilon Imprimatur and could warp their biodata. (PROSE: Interference - Book One)

The Hermit taught it to the Doctor; when the First Doctor revisited the hermit toward the end of his life, the Hermit transmigrated a bone-china tea set and the Doctor transmigrated a jug of yak's butter, though it was ugly due to rheumatism stiffening the Doctor's wrist. The Hermit noted that the Doctor always did better at transmigration while his hands were in his pockets. (PROSE: The Three Paths)
