Details
The modus operandi of Charissa marks her as a False prophet of the Pilgrims of Hayte although the individuality of the False Prophets means this provides little guidance as to her actions.
Her orgins have been traced to Malfi where it seems she was a member of one of the lesser noble houses (Her house and all records of it have been purged by Inquisitorial order) it seems she was recruited in to the cult during the Blood Solstice on Malfi , evidence shows that she was already a heretic and sorceress before her recruitment.
She has been definitely linked to 4 major events and is suspected of involvement in other atrocities. Before her full notoriety was reached she was arrested by Arbiters on Belespine, there by means unknown while held prisoner she subverted the prisoners in the Belsavis precinct and escaped leaving the whole precinct of Arbiters dead and the building in the hands of the renegade prisoners. The precinct house was reduced in a 3 month siege by elements of the Imperial Guard and Arbiters.
Next confirmed presence was the Fenksworld Flesh Riots, an uprising by a cannibal cult killed 3 million imperial subjects in the chaos and notable reduced the industrial output of the hive. The cult was using bound demons and was only put down so quickly due to the fortuitous presence of a squad of Greyknights hunting a different demonic presence. Interrogation of survivors revealed Charissa was the founder and leader of he cult who disappeared just as their attack began.
The Lathe heresy slaughter. A signifigant number of tech priests in Forge 3A67delta were converted to a heretical belief in the doom of all mankind and converted their forge workers to combat servitors and skitarri before launching an assault on several other forges and worker habitats. Putting down the uprising took 4 months and orbital bombardment by the orbital lance batterries and production of some material has still not recovered to pre crisis levels. Again traces indicated that Charrissa had spent time at the forge before the crisis broke out.
The Piety war, recruitment of Fraternis militia on Piety went disastrously wrong when the militia instead of embarking for crusade launched a crusade of purity aimed at eliminating all leadership figures in the Hive Piety-abstentious. The rogue militia took control of the local PDF and law enforcement facilities and were able to control the entire hive apart from the Arbiter precinct house which held out for 8 months. PDF and imperial guard forces from other hives sieged the hive for 12 months before achieving a break in when Astartes forces form the Smoke Jaguar chapter seized the gates. Inside the Hive a charnel house was discovered the combined imperial forces where unnable to fully exploit the breach after coming into contact with massed Dybuk and mutant forces lead by several Daemonhosts. Selective strikes ordered by inquisitor Marrissa failed to eliminate the daemonic threat and finally Inquitors Marrissa and Justice sanctioned the destruction of the Hive by bombardment from warships of Battlefleet Calixis. Total imperial casulaties 2 billion , purges , riots and crises in other hives added another 500 million.

She is also suspected in involvment in the Elros Night of the Maiden blades, The Lind Wyrm cult slaughter, Hilarion Grain war and Tephaine uprisings.

I did have stats for her but I don't anymore
