Not much is know of Abel's past, when his name first came to the attention of authorities he was working for the most nefarious gang in Lower Coruscant and had been working for them for a very long time. If the gang needed information from someone, Abel was their man. An expert in gathering information by any means from manipulation to torture, so infamous was he that the criminal underworld only spoke his name in whispers and hushed tones. For a long while no knowledge could escape him and none were left to speak his name, so Abel was mostly unknown to the public of Coruscant, only rumors lingered.
