The Lunalith is the most sacred object in the Orthodox Papal State of Lunaria and is the cornerstone of the Lunarian Faith.
The Lunalith is described as being a black, monolith that is approximately 5 to 6 meters tall and 2 meters wide. It normally emits a pale light. Due to its importance, it is kept inside the main church in the capital city of Yumuen. The security protecting the artifact is extremely tight.
The Lunalith's origin begin with the origin of the Lunarian Faith itself, during the chaos that appeared at around the same time as the founding of the Elfrieden Kingdom. Where the Lunalith came from is yet unexplained, but it became the medium in which the oracles of the Goddess Lunaria would send down to her followers. As such, only the pope is said to be able to interpret the oracles and name individuals as saints, such as Mary Valenti.
How and when these oracles are received is unknown, but it is through these oracles that the Papal State was formed and is how the government is run. Surprisingly, Merula Merlin was able to receive an oracle when she touched it, but she is so far unable to decipher the oracle's meaning.
