Founding - Ultima Founding (ca. 999.M41): The Ultima Founding of Space Marine Chapters has occurred in the wake of the fall of Cadia during Abaddon the Despoiler's 13th Black Crusade. The scattered Space Marine Chapters of the galaxy have been bled dry over the millennia of ceaseless battle.With the advent of gigantic Warp Storms that swallowed whole star systems, the formation of the Great Rift and constant attacks by the forces of Chaos, rampaging xenos and more, the Adeptus Astartes were stretched thinner than ever.With many Chapter planets now actively under siege, some Chapters were confirmed as destroyed or lost, and even those faring relatively well suffered high casualties and were in desperate need of reinforcement.With the resurrection of the Ultramarines Primarch Roboute Guilliman, the Avenging Son assumed command as Lord Commander of the Imperium over all of Mankind's military forces. He put into action his ultimate contingency plan, 100 Terran centuries in the making -- the Primaris Space Marines.These new transhuman warriors are the next step in the evolution of the Emperor's angels of death. They have been genetically altered according to a design laid down by Archmagos Dominus Belisarius Cawl of the Adeptus Mechanicus.Compared to their Firstborn brethren the Primaris Marines are bigger, stronger, faster and more genetically pure. The Primaris Space Marines of the Ultima Founding -- who have been added to existing Chapters as well as raised among entirely new Chapters of their own -- represent a timely and massive reinforcement for the Imperium's armies as Humanity's enemies close in for the kill.Chapter NameChapter IconProgenitor ChapterLegion NumberAngels of DefianceDark AngelsIBlades of Vengeance 	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/3/3e/BoV_SP_2.png/revision/latest?cb=20171222001727" class="image"><img alt="BoV SP 2" src="https://static.wikia.nocookie.net/warhammer40k/images/3/3e/BoV_SP_2.png/revision/latest/scale-to-width-down/210?cb=20171222001727" decoding="async" loading="lazy" width="210" height="169" class="thumbimage" data-image-name="BoV SP 2.png" data-image-key="BoV_SP_2.png" data-relevant="1" data-src="https://static.wikia.nocookie.net/warhammer40k/images/3/3e/BoV_SP_2.png/revision/latest/scale-to-width-down/210?cb=20171222001727" /></a> 	 		 			 		 		 		 	 Dark AngelsIAstral BearsPict-File UnavailableWhite ScarsVStorm Reapers 	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/3/39/StormReapersBadge.png/revision/latest?cb=20181220165009" class="image"><img alt="StormReapersBadge" src="https://static.wikia.nocookie.net/warhammer40k/images/3/39/StormReapersBadge.png/revision/latest/scale-to-width-down/210?cb=20181220165009" decoding="async" loading="lazy" width="210" height="173" class="thumbimage" data-image-name="StormReapersBadge.png" data-image-key="StormReapersBadge.png" data-relevant="1" data-src="https://static.wikia.nocookie.net/warhammer40k/images/3/39/StormReapersBadge.png/revision/latest/scale-to-width-down/210?cb=20181220165009" /></a> 	 		 			 		 		 		 	 White ScarsVIcefangsPict-file UnavailableSpace WolvesVIIron DrakesPict-file UnavailableSalamandersXVIIIWolfspearSpace WolvesVISons of the PhoenixImperial FistsVIIKnights of ByzantiumIron HandsXBlood ScythesBlood AngelsIXKnights of the Chalice 	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/1/1d/KoC_SP.jpg/revision/latest?cb=20230808223708" class="image"><img alt="KoC SP" src="https://static.wikia.nocookie.net/warhammer40k/images/1/1d/KoC_SP.jpg/revision/latest/scale-to-width-down/210?cb=20230808223708" decoding="async" loading="lazy" width="210" height="184" class="thumbimage" data-image-name="KoC SP.jpg" data-image-key="KoC_SP.jpg" data-relevant="1" data-src="https://static.wikia.nocookie.net/warhammer40k/images/1/1d/KoC_SP.jpg/revision/latest/scale-to-width-down/210?cb=20230808223708" /></a> 	 		 			 		 		 		 	 Blood AngelsIXCastellans of the RiftUltramarinesXIIIFulminatorsUltramarinesXIIIKnights CeruleanPict-File UnavailableUltramarinesXIIIPraetors of UltramarPict-File UnavailableUltramarinesXIIIPrime Absolvers 	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/6/6d/Prime_Absolvers_Armorial.png/revision/latest?cb=20220615062830" class="image"><img alt="Prime Absolvers Armorial" src="https://static.wikia.nocookie.net/warhammer40k/images/6/6d/Prime_Absolvers_Armorial.png/revision/latest/scale-to-width-down/210?cb=20220615062830" decoding="async" loading="lazy" width="210" height="182" class="thumbimage" data-image-name="Prime Absolvers Armorial.png" data-image-key="Prime_Absolvers_Armorial.png" data-relevant="1" data-src="https://static.wikia.nocookie.net/warhammer40k/images/6/6d/Prime_Absolvers_Armorial.png/revision/latest/scale-to-width-down/210?cb=20220615062830" /></a> 	 		 			 		 		 		 	 Dark AngelsIVoid Tridents 	 	<a href="https://static.wikia.nocookie.net/warhammer40k/images/0/0f/Void_Tridents%27_Chapter_Badge.png/revision/latest?cb=20181219092121" class="image"><img alt="Void Tridents&#39;
