Member of “Owls of the Forest”, Timber’s resistance group.
Rinoa Heartilly is a member of the Timber resistance group “Forest Owls”. Throughout Final Fantasy VIII, she becomes a Sorceress, gaining superhuman powers.
So when did Rinoa call Squall to World B? One scenario is during the Battle of the Gardens. During the battle, she falls off the Balamb Gardens yet clutches to the cliff. For whatever reason, Zell and Quistis want Squall to save her. He’s some time away, and it takes about ten minutes to reach her. How exactly does she hold on to the cliff, unless Materia calls her to World B? Of course, upon returning she would return right back on the cliff, or on the back of Squall’s Galbadian jetpack.
Another scenario is when she loses control in space. At the Lunar Base space station, Ultimecia takes control of Rinoa. After unlocking Sorceress Adel’s space-bound tomb, Ultimecia leaves Rinoa to die in space. While in space, she loses oxygen. How does she survive? Perhaps Materia calls Rinoa to World B. Of course after she grants Materia her crystal form, she would arrive in space with lowered oxygen.
The most likely scenario is during the Time Compression. Near the end of Final Fantasy VIII, all of our party members find themselves stranded in time. The only way they can make it back is by remembering their friends. Of course, Rinoa remembers Squall and sets out to find him. In Final Fantasy VIII’s world, she eventually finds him. However, she might have gone to extravagant lengths, by finding herself in World B.
