Blackwater Palace
This grand Harkonnen palace rises in the city of Carthag on Arrakis as a fortress of wealth and discipline rather than comfort. Its blackened halls are cooled by hidden systems, its floors gleam without a speck of sand, and its courtyards are arranged to catch only the shortest, most controlled shafts of desert light. The building serves as a residence, command center, and symbol of domination, housing the routines of spice administration, political theater, and private cruelty under one immense roof.

Blackwater Palace
Cold, severe, and immaculate. The air smells faintly of spice, polished metal, and filtered water. Even in silence, the palace feels watchful, as if every corridor expects obedience.

History
Audience and Protocol
The palace maintains a formal audience schedule for planetary nobles, spice brokers, military officers, and tribute envoys. Visitors are searched at the gate, then escorted through mirrored antechambers where servants record every word. No one enters the inner court without a summons sealed in black wax.
Security Measures
Household security is handled by disciplined guards, pain-dosed interrogators, and hidden sensor nets built into the walls. Windows facing the desert are narrow and high, while access corridors are deliberately long and easy to seal. A sealed lower chamber holds emergency water reserves, escape gear, and records of the palace staff.
Public and Private Wings
The manor contains an upper banquet hall, a private strategy room, and a gallery of trophies taken from rival houses and desert campaigns. The finest rooms are reserved for spice lords, off-world emissaries, and family retainers trusted with sensitive business. Every chamber is arranged to impress, intimidate, and remind guests that wealth here is measured in control.
Archives and Ledgers
Beneath the main floors lies a restricted archive of shipping tallies, land deeds, bribe ledgers, and desert intelligence. Most of it is mundane on paper, but together it reveals the entire supply web of the city. The records are guarded more carefully than treasure, because in Arrakis, information is often worth more than spice.
Denizens
Cruel, disciplined, indulgent in private, and obsessively controlling in public
Chief steward of the household, responsible for schedules, supplies, and discipline. He speaks softly, keeps exact records, and never forgets a slight.
Commander of the palace guard, a veteran of desert raids who values order above loyalty. She respects strength, distrusts charm, and watches everyone at once.
A quiet record keeper who manages spice tallies and shipping notices. He appears harmless, but he knows which names belong on bribe lists and which belong on death lists.
Rumors & Plot Hooks
- 1.The palace cistern contains enough water to buy a small army, but only the owner knows the true amount.
- 2.A hidden passage leads from the lower archive into a sealed tunnel beneath the city.
- 3.Several servants are actually informants planted by rival interests, yet none know the identity of the others.
- 4.The trophy gallery includes a sealed case that no one is allowed to open because it holds something still alive.
Classified Entry
Behind a false wall in the ledger archive is a concealed control chamber that tracks shipments, bribes, and the movement of key rivals across Carthag. The owner uses it to manipulate the city’s trade and to identify anyone who might threaten Harkonnen control before they can act.
