"Until their essence fades to nothing in the Land of the Dead, the spirit yet remains. Knowing that, one wonders if it may yet be
	possible to restore those lost to us, that we may no longer mourn their absence. They would require a connection - something to
	anchor them to who they once were and to the worlds from whence they came, and a spark of life. Could the latter, perhaps, be
	borrowed from another? And how would one share themselves so, without endangering their own life?"

How could one share a spark of life with someone who is dead without endangering their own life? Our hint for this question is DUST.
