We all know about the Machine God, that strange Saviour Machine experiment of the God Learners, but as part of an experiment with the University of Yoranday, the God Learners also created an imaginary deity Jogrampur, worshiped alongside other anthropomorphized sorcerer-deities such as Worlath, Ehilm, and Humct. In 901, the priests of these artificial cults displayed effective Rune Magic and destroyed the University of Yoranday, proving at great cost that any path to magical truth can result in real power – even that completely made up.
Please note that Belintar is not Jogrampur.
And that is an important thing – there is a tendency for people to want to connect the dots, and fill in between where they think the lines are. Jogrampur shows you that there are dots you never imagined and the lines go far further out than anyone assumes.
Any path to magical truth leads to magical power. Even if they are completely made up. It is just harder to get there and less likely that the path leads anywhere.
There are gods even without worship or belief. And they have power even if we do not know who or what they are.
