Larissa " Larissa " ( also called the " little book " and " the Jesuitess " ) was a member of House Dvora who joined the Order of the Weal and became Chatelaine Thessalia ' s mnemonic . After the babel killed Thessalia , Larissa went to 17th century Earth to avenge her ; this brought her into alliances with Aphra Behn and , later , Faction Paradox . Biography . She came into the world as part of House Dvora ; after the fall of the Imperator , she and her cousin were sent to live in House Ixion , where the housekeeper frightened her . Years later , she joined the Order of the Weal and was recruited to be Thessalia ' s mnemonic . The housekeeper called her " my little book " . When the babel attacked the housekeeper on the frontier in time , it left the little book alive , hoping she would follow it to Earth so it would be able to use her as an exit route after carrying out its plan . Indeed , the little book mercy - killed the housekeeper and immediately started plotting to defeat the babel . She was picked up by posthuman scavengers and bought a time - aware bio - suit that allowed her to travel through time . After hearing rumours from Civitas Solis about ripples in time , Larissa used the suit to go to 17th century England . Faction Paradox ' s anti - Homeworlder " loa " stopped her from being able to speak any recognisable language , and Larissa killed everyone in her way before being subdued by physical effort . Since she appeared during an anti - Catholic craze , Corinthian Tom bought her and he marketed her as " the Jesuitess " , sent by the Pope to asssassinate the King . He presented her from the House of the Infernal in 1678 . Hearing that Faction Paradox had an interest in the Jesuitess , Doctor Bendo sent Aphra Behn to preemptively buy her from Corinthian Tom . However , Tom would only sell the Jesuitess ' sleek black skinsuit , which Aphra decided to keep for herself . When Faction Paradox infiltrated the House and restored the Jesuitess ' power of speech while trying to kidnap her , an angry anti - Catholic mob attacked the building ; in the chaos , the Jesuitess escaped and began to search for her skinsuit . When Ratcatchers arrived to quiet the mob , Cousin Greenaway pretended to be the Jesuitess so she ' d be brought into Bendo ' s base of operations , where she overpowered the guards with her whip and stole the egg . At Aphra Behn ' s house , the Jesuitess arrived to reclaim her skinsuit ; however , Mother Sphinx and Doctor Bendo had traced her there , and Bendo shot the Jesuitess in the abdomen . Wounded , the Jesuitess erased him from time with the continuity needle and fled down Aphra ' s timeline , which her suit read upon tasting Aphra ' s blood ; in the process , she regenerates into a new form . A nymph appeared in a house near young Aphra Behn ' s house . Eff thought she was a nymph and pledged herself to her , naming her Larissa . Larissa travelled through Aphra ' s life , looking for moments where she interacted with temporal anomalies . This led her to appear in the Salomon House to ungag Aphra and knock one of the Service men unconscious ; Larissa and Aphra confronted Nick Plainsong , but before killing him , Larissa realised that though he was a temporal anomaly , he was not her target . Many years later , Larissa guided Aphra through London to a church where Nick Plainsong was showing the Faction Paradox shrine to Jeova Unus Sanctus and Nate Silver . Seeing the babel within Jeova , Larissa attacked him , and the babel entered her . Furious , Aphra stabbed Jeova with the continuity needle , causing the ripples in time that Larissa originally followed ; Aphra also destroyed Larissa ' s skinsuit to stop the babel from escaping . Finally , Cousin Greenaway and Erasmus together destroyed the babel and saved Larissa . Now without a plan to leave Earth , Larissa allied with the Faction . ( PROSE : " Newtons Sleep " )
