Even now I'm strapped for time, so I'll just copy and past the public parts of the official report:
On December 9, 2011, the sixth person to bear the title of Analyst Alpha spearheaded an act of dissidence against the Archive. Without receiving proper consensus from the Council of Seven, AA secured the aid of the tenth Martyr Alpha and the seventh Broker Alpha and began a campaign of aggression.
She began by ordering Martyrs to assassinate the third Keeper Alpha. Following this assassination, AA and her follows launched an all-out attack on the Sphere. Her objective was to obtain the twelfth Scribe Sigma and the entity known as "Neomaria." It is believed that she wished to perform a fetal transplant from Neomaria to SΣ.
On December 19, 2011, Martyrs penetrated the Sphere. The eleventh Inquisitor Alpha was subsequently killed. Both of AA's objectives were secured.
On December 20, 2011, AA attempted to perform the Fetal Transplant. *CENSORED*
AA's remains were then recovered by a team of Collectors. Neomaria's whereabouts remain unknown.
Following a tribunal hearing on December 26, 2011, it was determined that MA and BA were coerced into aiding AA. They will retain their positions. SΣ's status as a fugitive has been revoked, and she has been restored to her position in the Archive.
