|“||My duty is to Klaus. The new order.||”|
Greta Martin was a witch and the daughter of Jonas Martin and sister of Luka Martin. As a witch, she was allegedly kidnapped by Klaus and forced into finding another way to break the Sun and Moon Curse without using a Petrova doppelgänger. However, it seems as though her allegiance to Klaus was more intentional than obligated. She performs the sacrifice and feeds Jenna her blood to complete the transition and was later killed by Damon Salvatore.
Greta was a member of the Martin Family.
In, Klaus (episode), Greta makes her first appearance, arriving to assist Klaus with moving his soul back to his original body and ultimately to break the Hybrid curse.
In, The Last Day, Greta teams up with Maddox to capture Caroline, Tyler, and Jules. She later take Elena to the field, there she gives the transitioning Jenna her blood, turning her into the vampire that will be used for the sacrifice.
In The Sun Also Rises, all the sacrifices are in place with Klaus' arrival, where Greta traps them all within a boundary spell of fire as she begins to cause the Hybrid Release Spell, beginning with the moonstone, followed by the sacrifices: the werewolf Jules, the new vampire Jenna, and lastly Elena; the Doppelgänger. When Jenna was about to be sacrificed she vamp-speeds to Greta and attacks her, though Klaus stops and kill Jenna, allowing Greta to continue.
After the sacrifice is completed, and the curse broken, Klaus begins to shift into a werewolf. Bonnie begins chanting the incantation of the storm spell to kill Klaus. As Greta rises to stop her, Damon speeds behind her, and breaks her neck.
