Wyr be able to bend Temperature, Density, Pain/Pleasure, or Knowledge?
For example, if you choose density, then you are creating and uncreating atoms. So if you shift the density of an iron bar and put it into a rock, then the rock would have more atoms, and the iron would have less. Or if you choose Memory, and you transfer the memory of the existence cats into someone's mind, then the memory will disappear from the original memory holder's mind.
