Duenna Derida

Duenna was the mother of Terra Derida, Guerra Derida, and Paxxi Derida. After Terra had been memory-wiped, she had turned dark. She had forgotten completly who she was. So Duenna lived in the Syndicat head-quarters, caring for Terra from not very far away. When Terra died, Duenna knew that Terra had remembered her old ways.
