Cawl Knows What Happened to the Lost Primarchs

There is one man alive in the 41st millennium who could end the galaxy's oldest argument with a single sentence.Belisarius Cawl has lived for ten thousand years. He served at the side of the Emperor's own loremasters in the days of the Great Crusade. He carries gene-craft secrets that even the Emperor classified. He rebuilt the entire Adeptus Astartes from the ground up — every Primaris Marine alive is the product of research he has been running, in secret, since before the Heresy ended. He resurrected a Primarch. And in all that time, across all that knowledge, on the one subject the entire Imperium whispers about — the two erased sons, the Second and the Eleventh, the Lost Primarchs — Belisarius Cawl has said exactly nothing. Not a denial. Not a hint. Nothing.
