I was listening to the book on CD "Dark king / lighting tower" and I started to wonder if all the primarchs are accounted for. The stories of how a few died is know but is that the case for all of them. So I decided to ask around and see if anyone has definitive proof of what happened to them all.
1st legion Dark Angels Lionel Johnson- recovering in stasis on the Rock
2nd Legion NO RECORD REMAINS
3rd Legion Emperors Children Fulgrim- Daemon Prince in Eye of Terror
4th Legion Iron Warriors Perturabo- fate unknown
5th Legion White Scars Jaghatai Khan- i believe lost in Malestrom?
6th Legion Space Wolves Leman Russ- Chasing off into Eye of Terror
7th Legion Imperial Fist Rogal Dorn- fate unknown
8th Legion Night Lords Konrad Curze- Killed by assassin
9th Legion Blood Angels Sanguinius- Killed by Horus
10th Legion Iron Hands Ferrus Manus- fate unknown
11th Legion NO RECORD REMAINS
12th Legion World Eaters Angron- Daemon Prince in Eye of Terror
13th Legion Ultramarines Roboute Guilliman- fate unknown
14th Legion Death Guard Mortarion- Daemon Prince in Eye of Terror
15th Legion Thousand Sons Magnus the Red- Daemon Prince in Eye of Terror
16th Legion Luna Wolves Horus Lupercal- Killed by the Emperor
17th Legion Word Bearers Lorgar- Daemon Prince?
18th Legion Salamanders Vulkan- Killed by Horus?
19th Legion Raven Guard Corax- fate unknown
20th Legion Alpha Legion Alpharius 1 & 2 Both fates unknown
so out of 21 Primarchs, we know what happened to nine? Is it just me but if all the Primarchs were so god like and only the "bad ones" are left why havent they just taken over.
