OK, basically, in the Bevelle-Zanarkand war, Lenne got called upon to fight on the front lines. Both she and Shuyin knew she'd die, so he went to Bevelle and revived this super weapon called Venagun, and planned to use it to destroy Bevelle and teach humanity the horrors of war. However, just in time, Lenne shows up and stops him. At that point, though, they're both shot down by Bevelle soldiers. Shuyin remains as an unsent, and over 1,000 years later (ie, 2 years after the events of FFX), possesses someone (can't rember who, exactly) and uses them to try and carry out his plan again - only this time, he plans to destroy the entire world, in revenge for Lenne's death because of war. He also posseses Yuna's aeons the same way Yu-Yevon does at the end of FFX. As Yuan, Rikku and a new character called Paine, you have to stop him. At the end, he and Lenne depart for the Farplane.
