Are you really at the council of seven? and do you talk to the imp? If yes he should give you the pyramids back.
If he doesn´t something has gone wrong with your game.
In this case delete all files in the
divinity\run\dynamic folder (not the folder itself) and try again.
If this doesn´t help save your savegame and reinstall <img src="/ubbthreads/images/graemlins/div.gif" alt="" />
