What power did Lomi Plo use here?
Luke says she's draining the lightsaber of it's energy, so that eliminates cryokinesis in order to freeze it. But I hesitate to call that power Force Drain... What could it be?
"The low throb of wings sounded overhead, and the hilt of Alema's lightsaber grew painfully cold as the thing causing the sound-he wondered if that could be Lomi Plo-drained the energy from its power cell. The blade sputtered and died."
