As Blakfuel became the mainstay power source for all internal combustion engines, its disadvantages became more and more apparent: for one, its state of matter was very susceptible to temperature changes. In hotter climates, it would burn abnormally hot and gave off a lot more fumes, making it volatile and dangerous to work with. At lower temperatures, such as those encountered in Domoya, it would thicken into a tar-like substance that would burn very cold and gum up internal combustion engines. Another issue is that, while it ran well and efficiently in engines, its explosive power was limited at best and produced a low torque ratio. While this was not as big an issue for aircraft and zeppelin engines, it made it difficult to utilize for heavy hauls without using an extremely complicated transmission system. Advances in blakfire refinement and alternative fuel would fix this, but the need for a locomotive that was relatively easy to maintain and could operate in all temperatures without modification had become apparent.
So, the engineers in Extremidad came up with the Chauncey, a steam locomotive fueled by Blakfire crystal. You see, while Blakfuel's burning temperature is unpredictable, unrefined Blakfire crystals, when heated with a regular fire, burn hot and consistent, much like this world's coal. The only downside is that the flames are hazardous to touch, but so long as safety precautions are taken, the flames can be contained easily like any fire. Of course, considering the nature of Blakfire flames to alter the very state of regular metals, the firebox and parts of the boiler of the Chauncey are reinforced with Blaksteel, which can survive the flames and abilities of blakfire flames.
The result of the Chanucey's novel power design is a robust, powerful engine that can operate in almost any environment, and pull around heavy loads like no one's business. In fact, the design is so effective that the Chauncey is used under licence by many countries, and has become a staple, and symbol, of overland world logistics.
- 4-8-4 wheel layout for even distribution of weight across the rails
- modular design allowing for additions such as side plates, cow catchers, and even full armor for military duties
- "knuckle" style couplings, based on the pre-world "Janney" coupler
- post-world "reversing" valve gear; utilizes a gear mechanism within the piston housing to reverse the direction of force from the crank arm (based off a simplified Walschaerts design) in order to operate the pistons. While deceptively simple, it allows for an effiecient management of the steam to the pistons, though the downside is that the gears tend to wear easily with continued use, prompting routine inspections. Most engineers carry spare gears in the cab in case one needs replacement away from the works.

"The secret to not dying on a Cherub is to always keep moving; As soon as you slow down every gun within a two mile radius will be trained on you. That, and stay close to shore. " - unnamed Extremi Cherub Patrol Boat Crew
Before the Cherub, Harbors were guarded by shore-based coastal defense batteries, torpedo nets, and the occasional cruiser or destroyer standing at attention at the mouth. While this is effective against large-scale raids, it was found lacking against smaller infiltration craft carrying saboteurs, small arms, or sometimes even high explosives and torpedoes, which would be either launched within the harbor or the entire boat turned into one large torpedo, with the crew locking the throttle and (hopefully) jumping free before impact. As these sorts of incidents became more prevalent, the need for a light, fast craft that could keep up with them was made apparent. At the same time, another growing issue was a lack of a fast, shallow draft boat that, ironically, would enable the Extremi's to carry out raids of their own, and in addition, a boat that could be sent up rivers to drop off and/or support small shore parties.
To deal with all of this, the Cherub came to be: Also called a "Mosquito Boat" or endearingly referred to by its crews as "Cheri" the Cherub proved itself as just what the Extremi Maritime Navy needed. Fast, reliable, and mission configurable, the Cherub came in two basic variants: The first was a standard "Ocean Patrol" variant, featuring traditional screw propellers/rudders and equipped with torpedo tubes for fast, brutal attacks against enemy ships and infrastructure. The second variant was a "River Patrol" variant, featuring a more advanced pump jet system and lightened considerably to allow for fast river operations. Of course, as with all small, fast craft, the Cherub is lacking in heavy armor, meaning her speed and maneuverability is the only things standing between her and Davy Jones' locker. In addition, despite her Ocean Patrol version having a deeper draft, her range is limited and larger swells can tip her over if her crew isn't careful, she is still not suited for independent open ocean operations, limiting her use to coastal duties at best (though there have been instances where several Cherubs have been operated in deep water from a "Mother ship" tender, allowing their use in naval warfare as fast, light raider boats.)
-Modular weapon design means Cherub boats can be configured for mission needs, and can support a variety of weapons
-River Patrol Version's impeller pump jets allow for fast shallow draft operations without fears of damaging the inner works, though the more complicated design leads to mechanical difficulties if not properly maintained.
-all variants equipped with basic short-range radar/sonar, allowing them to act as "spotter" ships for Leviticus class destroyers on submarine patrols. However, due to their limited usefulness in river ops, many river patrol captains elect to remove the sonars to save on weight.
-Equipped with a small launch behind her exhaust stacks, useful for landing troops/as an emergency raft
-While space is limited, Cherubs also have a small berthing and simple galley with stove, allowing for some crew comfort.
-Navigation/radio room located just fore of the wheelhouse and aft of the forward gun
