Editing Extinct chapters (section)

== Celestial Swords... and Celestial Swords ==
{{main|Celestial Swords}}
In an epic failure of Imperial bureaucracy, these two chapters were founded with identical heraldry and names in the 38th Millennium in an unknown founding and from an unknown lineage at the same time. The mistake wasn't discovered until both Chapters went to the same engagement against the 9th Black Crusade (537.M38) and were both wiped to a man and the bodies of nearly two thousand Battle Brothers were found in the Cicerine System. In a small stroke of mercy, both Chapters were wiped out within the same millennium they were founded in and in the same engagement, preventing further confusion.
