One of three apparent children stranded with Tuvok on a Drayan moon, in reality an aged Drayan who has come to the sacred place to die.
Corin is a Drayan. He appears in the second-season Voyager episode Innocence.
Tuvok crash-lands a shuttle on a moon and finds three frightened youngsters, Tressa, Elani and Corin, who say their ship has crashed and that a creature called the morrok comes in the night. Tuvok looks after them and calms them with Vulcan discipline and a lullaby.
During the night first one and then another of the children vanishes, leaving only clothing behind. The truth is that Drayans age in reverse: Corin and his companions are at the very end of long lives, their minds clouded, and have been brought to the crysata to pass away peacefully. Only Tressa is left when her people arrive.
