Editing MidHammer 40,000: SM Chapters (section)

===="The Corvidae Founding" (M33)====
The Fifth founding came about as a result of a the First Black Crusade, when several legions (the Iron Hands in particular) learned the hard way how painfully ill-equipped they were for war against demonic forces. While orders like The Grey Knights did exist, they were small, and the Inquisition's "Ordo Malleus" was distrusted by most, if not all Space Marine Legions. Thus it was Magnus The Red's Turn to Donate, and as Such Composed The Regula Prosperae, providing for new Psyker-heavy Chapters, and ways to guard them against Chaos. Note that very few Thousand Sons formed successor chapters due to issues with the Primarch's geneseed. Until the development of Primaris the Regula Founding was mostly composed of other chapters (White Scars in particular).
