So who lived and Became Eternals? This is just speculation but could our past heroes have been scooped up by Sigmar?
A direct quote of the, albiet merger fluff...
The great heroes of the realms were torn from their lives and transported to Azyrheim...
... There they were reforged in to champions of order
Could that mean that guys like Markus Wulfhart (Who appears too have lived) are now Eternals?
