Management is a Kafkaesque bureaucracy who's internal structure more closely resembles the infinity effect of two mirrors facing each other than any rational, mortal organization. Management maintains a presence on all planes of existence, though for what purpose is unclear as Management rarely intervenes in material affairs. It's field offices are well hidden and can be located within twisting alleyways, past the door in the back of the bar you only ever see out of the corner of your eye, and behind you. 

Occasionally, Management will take an interest in mortal affairs for their own unknowable reasons. Sometimes they will allow a representative from headquarters to requisition a material form and investigate in person. Other times they will recruit a representative from the material plane, with payment coming in the form of power given in exchange for information. It's unclear what draws managements attention to certain events. What is clear, whether they are the underlying cause or merely a response, wherever the representatives of management go the laws of the universe have shattered and madness will follow.

Unlike their colleagues, Management Warlocks use intelligence rather than charisma to cast spells and refer to Eldritch Blast as their "Service Weapon". 

Unworldly Mind

Management is a constant, silent presence in your mind. There is no moment when you are not reporting back to them. As such, you do not communicate through verbal language. Instead, you communicate telepathically, dictating your actions back to the ever listening management in the form of hardboiled voiceover narration. The minds of beings unused to contact with the unknowable will subconsciously protect their own sanity by perceiving you as having spoken normally. Prolonged communication will make them increasingly uncomfortable and they will eagerly answer your questions in order to end the interaction more quickly. 

For Example:

Tavern Keeper: "Can I get you something to drink?"

You: "The lights were low and I could see a single bead of sweat hovering above the barkeeps pudgy lip. The thought of drinking material liquid disgusted me but I could feel this mortal forms thirst and there were more important things at stake than my discomfort. I ordered an ale and leaned back in my chair."

Tavern Keeper: "One ale coming up sir!"
