The Sea Emperor will be capable of telepathy, and will speak to the player about the need to hatch her eggs. Most likely it found some way to tell them it.

Or in the other scenario, they learned over time that the sea emperor was the only thing keeping them alive from Carar, meaning they learned to protect it, and also learned that the Warpers will try to kill infected creatures, so they defend you from the warpers too.
