Lucidique is one of the Supplicants of Agonistes. Even before becoming a proper Supplicant, she was a follower of Agonistes - or at least knew of him enough to meet him personally and arrange meetings between him and a potential Supplicant.
In her human life, she was the daughter of a Senator who was critical of Primordium's ruling class, the decadent Perfetto Dynasty. To quell his whistle-blower, the Emperor Perfetto XI commissioned the gangster Don Duraf Cascarellian to send an assassin to rid him of this Senator. This assassin would be Zarles Kreiger, who would come to be known as the Scythe-Meister as well as Lucidique's ill-fated lover.
