Silenia is the leader of the Sators. A Deceiver through and through, it is said that Silenia is the left arm of Electrotyrant while Syphene is the right.
Both are highly valued by Electrotyrant, especially when the bulk of his forces are barely cognisant automatons.
Silenia and her Sators sided with Galaxy Tyrant in his rebellion and were subsequently imprisoned for their actions. Now with a physical body and a permanently corrupted code, Silenia serves Electrotyrant for a time until she and her Sators can find a weakness and usurp his Tyrant status.
Dark Angel was an unremarkable Deceiver until she came across a hidden room within the COILS lab that was destroyed by the Deceivers. Within this room was an experimental weapon obviously being developed by the COILS scientists before their destruction. It didn’t take much for Dark Angel to ready this weapon for her own use. Now Dark Angel never leaves her weapon lest it fall into another Deceivers hands.
