The Legendary Hero Temple is a temple in Elemakstro, Kahran that was constructed to honor an ancient "Legendary Hero". Predating the invention of the Kahranian language by a million Kahranian years, it is not very clear who the Legendary Hero was or what he did. It is believed it had something to do with an entity similar to Destonator, but Destonator had not existed until 988,000 years after this temple was created, and it was Light who destroyed him.
The temple, when seen from the outside, looks old, but not very much. It has cracks in it, with many of the statues broken. However, this is because the temple was placed with no care onto Cavius by Destonator. Before that, the foundation was very well preserved, and it was located in a cave. There are stairs that lead to the entrance, which is guarded by two statues of the Legendary Hero. The columns holding the stairs are in 8 different colors, and there are three statues of what can presumably be Shalos. The entrance has some triangular panels that are, again, in 8 different colors. Their use and purpose is unknown. The temple has turned from silver to greenish because of a special chemical compound in Cavius' atmosphere. The inside has many more statues, and also has a giant room with a giant throne and two smaller ones. Destonator sits at the giant throne while waiting for the Heroes in the FDUS. Firis spends his time in the one of the small ones, and Exzo in the other. On top of the temple's exterior, there is a miniature Kahran globe, which is unbelievably accurate.
