Lust was Father’s second creation, something very near perfect, but not made completely in his image. Meaning she was another facet of him, one he did not look upon often, and who could reflect a different view point back to him. That is why she is tasked with so many tasks while serving him; from raising, training and monitoring the Homunculi that were created after her (sans the reborn Greed), filtering through raw information and creating reports for him, monitoring research projects and experiments done outside of Central’s labs, being his Emissary, carrying out delicate missions, and being a ‘ quote on quote ’ assassin as well.
Lust works tirelessly under Father, rarely resting or taking time aside for herself. She is incredibly efficient and has a very high success rate with her plans.This is why she could easily step into Pride’s ‘place’ while he was above ground masquerading as Bradley’s son. She is a decent leader, being concise and not tolerating misbehavior, while still retaining tact and manipulative persuasion.
Lust’s main operation ‘hub’ is a giant, underground library that is connected to Father’s domain. This library contains all confidential information, ancient texts, information sent in from plants in other countries, and copies of all records of persons-of-interest. She spends a good amount of her time there, pouring over the information, condensing it, and creating reports to be shared with Father and the other Homunculi; namely Pride, Envy, and Wrath. Her bedroom is attached to this library and many books spill into the bedroom, though some of these books are more ‘light’ reading, and not as work specific.
She will take rare breaks and go into her room and read in her bed, sometimes not sleeping at all in favor of reading.
