No one is quite sure what Bolingbroks goals actually are, and who or what he truly serves. But he certainly seems to be widely travelled across the entire planet, and the pattern of shipments of tech disappearing soon after he has been spotted in any given locale is very well known.

A strange little mechanical beast that seems to be something of a good luck charm for Bolingbrok. Some say it is an abominable intelligence, but others believe the consciousness within the machine may be something else even more monstrous...

Gamma-Bom-32 was originally a member of a tribe of diminutive nomads from the Ash Wastes, notorious for scavenging and stealing technology from lost travellers. No one knows how he came under Bolingbroks influence, but they certainly share many interests...

Ghost is thought to be a former marksman in the Imperial Guard, once completely dedicated to the Imperial cause.  This all changed when an encounter with an Aeldari heat weapon left him without three of his limbs and abandoned by the military he loved. It is thought Bolingbrok was able to manipulate the bitterness burning inside Ghost, and after a gift of new mechanical limbs the Esotechnician gained himself a dedicated and determined bodyguard.

Lord Varlak was said to be a heretic psyker that once attempted to lead a planet in revolt against the Imperium. When that was bruttaly suppressed it was said he escaped to Necromunda. Tall tales say that the once influential leader Varlak has now become a subjucted follower... 

If true, how he came to be a severed head kept 'alive' by diabolik technology and weaponised by an anonymous bearer is unknown. But whatever the facts, the Head seems to be a very useful weapon in Bolingbroks arsenal...

The man who would become Lobo was once your standard Underhive scum, a gun for hire with little hope for the future. The problem was, he really wasn't very good. His aim was awful, and he had a tendency to panic and flee when things looked even slightly intense.

Bolingbrok claimed he could help these problems with glorious technology. And after the introduction of a chunky cranial implant, both of these things certainly improved significantly. That he shows little other personality or independence now is of no importance. Bolingbrok has another dedicated acolyte.

Claw sought out Bolingbrok herself, fascinated by his dark reputation. Her family were always given a wide berth amongst the denizens of the underhive, apparently always meddling in impenetrable, unknowable mysteries beyond the understanding of regular folk. Claw was suposedly more fascinated in these mysteries than her sister Slice, a born tinkerer, but both found a suitable mentor in the Esotechnician.

Slice followed her sister Claw into the company of the Esotechnician, but she was always more interested in learning his technological secrets than his knowledge of more arcane 'sciences'. Still, she has proved just as dedicated to the cause as her sister.

Stapler was going nowhere until Bolingbrok found him. Though not quite as hopeless as Lobo was, he was still enticed into serving the Esotechnician with the promises of technological improvement. His new headgear doesn't sem to really have improved his skills much at all, but he always comes when he's called now.

Bolingbrok appears to have access to a number of Tech-thrall servitor warriors. Rumour has it that these were given in payment for services rendered, or to help further an unknown hands cause...

Another mindless zombie tech thrall. Reliable, if having zero of its own initiative. Still more entertaining company than Lobo.
