Riina Kwaad
this was the name given to Tahiri Veila by the Yuuzhan Vong Mezhan Kwaad, during her attempt to twist Tahiri's memories and create a living bridge between the Yuuzhan Vong and the Jedi Knights. After Tahiri was rescued by the Anakin Solo from Yavin 4 and given a chance to recover, the personality that was Riina remained deep in her subconscious. It began to reassert itself when Tahiri encountered something that was imbued with the Yuuzhan Vong spirit, such as a pendant of Yun-Yammka she found on Galantos. When this happened, Tahiri was plunged into a deep state of unconsciousness, where Riina took control of her mind and tortured her. After several blackout incidents on the planet Bakura, Jaina Solo discovered that the Riina Kwaad personality inside Tahiri's mind still existed, and was rebelling at the possibility that it might be cast out of Tahiri. The blackouts she was experiencing were Riina's attempts to cast out Tahiri's own personality. Riina would have been fully eliminated if Tahiri hadn’t experienced the death of Anakin Solo, which triggered doubts within Tahiri's mind. The Republic's victory at the Battle of Ebaq then reinforced the belief that the Republic was winning the war against the Yuuzhan Vong, and Riina began asserting herself more fully in order to avoid complete extinction. Further investigation into the Tahiri/Riina relationship revealed that it had been Riina, not Tahiri, who created a Force bubble to protect Tahiri from the bomb set on Bakura by Blaine Harris. This pointed to a much deeper melding of the two personalities than was first believed. Within Tahiri's mind, the two personalities struggled for control, before both came to the realization that they had to unite in order to survive: if one were killed, the other would die as well. In the end, the two agreed to meld into a single individual. Tahiri's peace was brief, for asfter she agreed to accompany Nen Yim and the Prophet Yu'shaa to Zonama Sekot, she discovered that the Riina Kwaad personality had ben created from the memories of Nen Yim herself.
