Changes

In the novella [[Fury of Magnus (Novella)|Fury of Magnus]], [[Alivia Sureka]] recalls, during her meeting with [[Magnus the Red]], how she had previously met four other Primarchs: [[Horus Lupercal]], [[Roboute Guilliman]], [[Corvus Corax]], and "one whose name she had sworn never to speak".{{Fn|56}} The latter may have been one of the two lost Primarchs, as various other people had also been ordered to never speak their names, or to discuss them and their Legions, after they were expunged from Imperial records.{{Fn|18b}}{{Fn|40}}{{Fn|42}}

On the official Horus Heresy website, there is a timeline listing a series of events occurring in the late 30th and early 31st millennia, including the rediscovery dates of the various Primarchs. This includes two events, labelled "Discovery of [REDACTED]", dated to the years 821.[[M30]] and 927.M30. These are presumably the discovery dates of the two lost Primarchs.{{Fn|57}} As [[Fulgrim: The Palatine Phoenix (Novel)]] confirms that the II Legion Primarch was among the first eight found, his rediscovery is presumably the first of these two events.{{Fn|36}}
