The Royal Postal Services is an independent organization focused on the delivery of mail and the operation of pneumatic networks. While formerly a Crown funded enterprise, they cut ties after the Whitestone controversy and subsequent assassination attempt on the PostMaster General.

The RPS is known for delivering any object, of any size, regardless of its sender, recipient, or contents. They commonly advertise themselves as having “Never lost a package”.

The RPS has always made a point of neutrality. They often clashed with the government due to their continued deliverance of mail to and from “enemies of the state” such as The Utopia Project, despite most of their funds coming from government grants. The service was considered crucial enough to the Kingdom's operation that disbanding it was not an option, so for some time it was allowed to operate (albeit under close scrutiny) as Crown strategists determined the feasibility of a takeover.

Tensions increased after an incident involving the Whitestone Hall Conservation Project, where a large explosion occurred underneath statesman James Whitestone's manor. It was found that a shipment of cement had contained a heat activated explosive, which was placed by an unknown operator and detonated as the cement dried and warmed up. Crown investigators found that this device was discovered during a routine RPS shipment stopover, but upon determining its activation method, workers simply relabeled the package as “volatile- heat sensitive” according to company protocol and sent it onwards to the construction site. This greatly angered Whitestone, who was supposedly injured by the blast, and he began lobbying for a complete takeover of the RPS as had been done previously with EastRock Electric.

This lobbying was successful, and a timed-release shipment of large canisters of sleeping gas canisters were delivered to a Crown airship yard. These canisters were lead, heavy enough to require processing at the central RPS depot, and declared as hydrogen composite lifting gas. The delivery was timed around a monthly depot inspection by the PostMaster General, a well-guarded and reclusive target. Agents were on standby to carry out an assassination as soon as the potent gas was released onto the depot floor.

The Crown, however, greatly underestimated the security capabilities of RPS scanners, which detected traces of the sleeping gas in the packaging and eventually determined the nature of the timed release device. The shipment was transferred to a safe holding warehouse, where the timed release was reset safely. The package was then marked as “hazard- chemicals” and sent onwards.

The defusal of the timer transmitted a small radio signal, which was meant to alert the agents that the gas had been released. They entered the facility and were immediately disarmed and detained by security.

The package arrived a government hydrogen storage facility. Employees, who had not been aware of any of this, attempted to pump the gas back into the holding tanks. The pressurized cannisters immediately ruptured the intake pipe and put most of the maintenance staff to sleep for several hours, as the entire holding tank slowly emptied though the open valve. This loss crippled government airship travel for several weeks.

This event was a major embarrassment for the Crown, who immediately cut funding to the RPS and began shift to the startup ShipRight for shipping needs. RPS officially became an independent corporation, and enjoyed a surge of business after word of their complete dedication to delivery spread. While their prices could not compare to ShipRight's, they remained popular for expensive, rare, or shady deliveries that required the utmost care and discretion.
