Liza's locket

Liza's locket is the locket of the late Alura Zor-El, later given to Tanya.

History
Liza and Tanya joined the Cult of Yuda Kal, though Tanya eventually left and stole Thomas Coville's journal. Liza and the cult then attempted to create Yuda Kal, the fourth Worldkiller with the leader, Olivia, as its host. However, without Tanya and the journal, they failed. The heavy metal reaction killed Liza, disintegrating her body, leaving behind her locket. Supergirl gave the locket to Tanya, who was heartbroken by her friend's death.
