[40K] What is The Emperor's name?

He wasn't always called the emperor. Heck, prior to the unification wars, he wasn't even *an* emperor. So for the 32,000 years prior to unifying Holy Terra, what was The Glorious Immortal God-Emperor of Mankind known by?

I have to break the fourth wall to get you the answer. It's never stated in the lore, but perhaps Malcador and parents knee. But every being in the universe has a true name, nobody knows Emperors. True names have massive power and Daemons can be banished back to Warp by saying it. M'Kar was banished back to Warp by saying his true name.
