Religion in Roo is not built around certainty. It is built around absence: temples to vanished gods, stories of a catastrophic war, and a newer Church that believes an ancient teacher named Drianor was divine.
The Vanir
The dominant older faith worships the Vanir gods. Freyr, Freyja and Njord are among the best known. Tradition holds that they were captured by the Aesir during the ancient war, while other Vanir died or disappeared. Many other Vanir gods are also remembered.
People believe the world itself bears the loss. Forests, mountains and seas remain beautiful, but the age in which the Vanir walked the world is understood as something greater than the present Age of Man. Temples to the Vanir are widespread across Roo.
The Aesir
The Aesir are not simply a rival pantheon in Rooan belief. They are viewed as evil, demonic or corrupt powers associated with the destruction of the old order. Whether every religious story about them is objectively true is another question. In Roo, belief and historical truth do not always occupy the same ground.
Drianor and the Church
Alongside the older Vanir tradition is a newer and growing monotheistic religion centered on Drianor. Its organized institution is commonly called the Church, with priests and developed theology. Believers regard Drianor as divine, although his true nature remains unknown.
This newer faith does not necessarily reject the Vanir tradition. Many believers understand Drianor worship and the older religion as expressions or continuations of the same underlying faith.
A man, a god, or something between?
Historical tradition remembers Drianor as a near-messianic figure who appeared after the Vanir–Aesir war, when the world had fallen into chaos. He tried to unite people and teach them to stop killing and stealing. He was eventually killed by an empire that still exists in the present age.
Later believers often describe Drianor as divine or godlike. What he actually was remains unresolved. One fact stands apart from theology: Drianor could activate and control ancient Vanir machinery.
What people know — and what they believe
The people of Roo live among ruins they cannot explain. Priests interpret ancient structures spiritually, while treasure hunters loot them and rulers sometimes build forts or castles into them. Functioning mechanisms can look like divine works to people who have no concept of machines.
That uncertainty matters. The official stories of the gods, the ruins and the ancient catastrophe are part of Roo's living culture, but they are not automatically the final truth of the world.
