Surprisingly, it is not from Rand. It is from one of his students, Vash Bloodcarver. You recognize the gaunt, slim figure in his black leather get-up and the miniature lightsaber in the hologram's hand.
The lightsaber is being held to a young woman's neck... and she looks exactly like you.
"Hello, Rianna," Vash says. "You may be wondering who this is." He pulls her hair and she cries out- in a voice that sounds like yours. "This... is your SISTER. I have your entire family here, held hostage. Come to Cloud City if you want to save them. We're settling this once and for all."
