Do we know for certain that Odin started the Dwarf Prophecy?

[xroads]

On the other hand, not only does Odin not remember doing it, but he is sure that it is not in keeping with his character to have done it. Now, maybe Odins personality is transforming through worship, or maybe he really didnt send his high priest and some other god did.... Loki?

I think it is definitely within the realm of possibility. Perhaps Odin received a vision and Loki was there when Odin verbalized the vision. Odin, either decided not to or was unable to act on the vision. But Loki could. So the god of trickery hatched a plan that as a bonus, involved kicking a cleric of his brother to the curb (by the cleric's own head priest).
