18. If the party returns to the Pharos at Ridorana after completing the story events there, they will find that the Dais of Ascendance allows them to access a new section: the Pharos Subterra. The Subterra has four levels, what are their names?
From Quiz An Eclectic Mix -- "Final Fantasy XII"
Answer:
Penumbra, Umbra, Abyssal, Unknown
The four subterra levels are filled with difficult enemies, darkness, and the absence of the mini-map. The first three levels are structured in the same way: a central ring with clusters of rooms at the NW, NE, SW, and SE areas. In each of these clusters there is an altar on which a certain number of black orbs must be placed. These orbs are received from enemies after defeating them. Only after all four of the altars in one level have been satisfied will the next level become available. All three upper levels must be completed in order to access the fourth level which contains the Shadowseer mark.
The other choices were made up except for Udii, Avaa, Praa, and Pratii. These are names used in the Great Crystal-Giruvegan to denote direction. Udii is north, Avaa is south, Praa is east, and Pratii is west.
