A young ryulent who lived in the ancient forest to the south of Yamato, Arbol took Ladius and his allies (who were lost in the forest) back to the home of the ryulent. With Ladius's help, he stopped the Grugund army from setting fire to his forest. Arbol has followed Ladius ever since. Arbol's race has existed for as long as the high elves. The memories and knowledge of ancient times that ryulent carry through the generations can't be duplicated by others. Ryulent are living documents that can provide recollections of the era of God, long before the ryulent themselves were born from the Tree of Earth. Grown ryulent travel to find a place where they can eventually rest in peace as a tree. Many ryulent have made this journey in the past, but as a dying species, they are remembered only in folktales. One of the reasons Arbol follows Ladius is to find his own final resting place and become one with the earth.
- In the Japanese dialogue of the game, Arbol use the pronoun Wagahai, which suggest an somewhat pompous mannerism of himself, but he use the suffix dono, an archaic term for lord, when addressing certain members of the party like Ladius and Borginine, which means he respects them greatly, but don't think any less of himself.
- Arbol's name is Spanish for Tree, fitting his nature as a Ryulent, which are plant-based lifeforms.
