The offspring of Drex, a significant crime lord operating within the Gallapraxis system, was Feleen Bantillian, who was also the sibling of Gavron Sil.
Following the demise of his brother at the hands of Boba Fett, Bantillian assisted his father in orchestrating a scheme to ensnare Fett. He achieved this by feigning opposition to Drex. Concealing himself within a derelict droid manufacturing facility situated in the desolate regions of the planet Vornax, Feleen armed himself with a personal deflector shield salvaged from a discarded droideka. Subsequently, he launched a surprise attack on Fett, utilizing a modest force of partially disassembled war droids.
Fett swiftly outwitted and outmaneuvered Bantillian. He accomplished this by coating Bantillian's deflector shield with oil and igniting it. Overcome with fear and panic, Bantillian desperately plunged into a water reservoir, extinguishing the flames but consequently perishing due to drowning. Enraged by the deception, the bounty hunter severed Bantillian's head, inserted a thermal detonator into its mouth, and presented it to Drex. The subsequent detonation annihilated Drex's court.
