Arceus

Arceus was at one point the central deity worshiped by all of the country of Altaria as a whole. It was believed to be a most benevolent God and was believed to be responsible for the creation of not only Altaria, but the world as a whole. It is currently unknown as the reasoning to how or why, but the people's faith in Arceus slowly began to decline as they took to worshiping other, lesser deities in its place. Shortly after this, Altaria began to go through several political and economic changes. Whether or not these were for the better or not vary, but people all agree these changes occurred because of their new deities. Despite it all, not one of the kingdoms took to worshiping Arceus again. The time of this great change in the country became known as "The Abandonment". To this day, Arceus' whereabouts are unknown, yet it is still worshiped with just as much passion as ever in the kingdom of Cantaras.
