Young girl on Lorien, Pittacus Lore, Possibly Four and Marina
Possibly Fire or Ice manipulation
"There had been the girl with the ability to manipulate temperature who'd accidently frozen herself to death in the bathtub..."
(Sandor, The Last Days of Lorien)
Temperature Manipulation is a Loric Legacy that allows the user to control the temperature of the air and of the objects around them. This can be used to heat or freeze objects in it's simplelist form.
It is unknown to what extent this Legacy can be used, though it is possible it can develop into Legacies such Cryokinesis or Pyrokinesis.
Six is able to change the temperature of the air as part of her Elemental Manipulation, having manipulated cool air around an airplane so that it could pass easily through a vicious thunderstorm over Kansas.
