In regards to the shaman origin
The Emperor's shaman origin was printed in Realm of Chaos: The Lost and The Damned
. A book from 1st Edition Rogue Trader. I own Realm of Chaos: Slaves to Darkness
and Realm of Chaos: The Lost and The Damned
as Christmas presents. Rick Priestley's Warhammer 40,000: Rogue Trader
book for 1st Edition Rogue Trader published in 1987 detailed the Emperor's birth, but not the shaman origin itself. The shaman origin printed in Realm of Chaos: The Lost and The Damned
is not just old, it is from 1st Edition Rogue Trader. 1st Edition Rogue Trader is, obviously, the very first edition of 40k. But, it is still there.
40K Retro Corner: Realm of Chaos - Lost and the Damned - Bell of Lost Souls
Here are links to YouTube videos for the book, and The Bell of Lost Souls site. Not imgur images or PDF sites like Scribd, so it should be fine.
