They don't want to reveal information that is too important. Unfortunately, the important information that they knew about this world was very small because even though they had the knowledge of their future selves, most of their future selves didn't reach the epic rank, so they didn't have access to much information about the world.
However, they still know a lot of knowledge that should be important to high-level beings, such as the absence of the pathway of creation and the absence of the pathway of destruction, even though the two pathways should exist.
Legion doesn't know why the two pathways disappeared and when they did, but they know that in the future, a god in control of the authority of the two pathways will appear and will take the title of the publicly acknowledged strongest god.
Legion isn't strong if this god is truly the strongest one, but they know for sure that this god will make the claim and shout it to the ends of the world.
