That has an easy solution: just don't explain everything and leave some stuff open for a sequel.

In the first Assassin's Creed game they didn't explain everything in the universe even though we were already surrounded by so much lore. The first film they introduce the Assassins and Templars struggle from the lore and introduce the POE right at the end.
