Niadra

Niadra is a broodmother created by Sarah Kerrigan when she battled the protoss on the remote world of Kaldir. Although she succeeded in preventing them from contacting the Golden Armada, one of the protoss ships attempted to flee from the planet and travel to Shakuras. To prevent them from surviving, Kerrigan placed a parasitic larva within the captured protoss colonist Lasarra and dropped the psionic veil that prevented her from being warped back to her people.

After being teleported to the ship, the protoss attempted to warn the templar but died as the parasitic larva spawned from her body. Shortly afterwards, it began infesting the local animals kept onboard by the protoss and hid within the ventilation shafts where it found a safe location to mature into a. This broodmother was known as Niadra and she was given the task of eliminating all the protoss onboard the ship which she did through her zerg offspring. She along with her forces managed to successfully eliminate all the protoss and prevent any of the survivors from fleeing within escape pods. After damaging the vessels warp drive, Niadra and her brood became the only occupants of the craft but they were severed from the psionic contact with the Queen of Blades. As a result, Niadra decided to continue her queen's last directive in order to survive, grow stronger, and destroy the protoss.
