Guardian Tree (Final Fantasy V)

The Guardian Tree is an elder tree in the Great Forest of Moore in Final Fantasy V.

It has been used to seal evil spirits by the people of Planet R for years and those evil spirits turned the tree into a creature with it on life, know as Exdeath.

Story
Inside the Guardian Tree, Bartz and his friends encounter the Four Crystals particular to Galuf's world, which attack them under Exdeath's control. Galuf saves the others from Exdeath, but at the cost: one of the crystals shatters, and Galuf expends the last of his life energy fighting Exdeath.

Exdeath takes the remaining three crystals to his castle. During the battle with Exdeath he succeeds in his plan to shatter the three remaining crystals, which triggers the two worlds to merge. In the process, the Great Forest of Moore merges with the Desert of Shifting Sands in the other world, and all the trees die save for a small grove around the Guardian Tree.

Galuf dies after the battle but he gave all of his abilities to Krile. Galuf tells Krile to fight Exdeath alongside Bartz and say he'll be always with her.

At the story's end only the Guardian Tree and its grove remain. It is hoped that, with the restoration of the the Four Crystals' power, the Great Forest of Moore will once again restore itself in time.
