Until recent times, Airships were a rare creation in Toril. Legend and lore of the Faerunian Continent speak of enchanted flying vessels built by the elves, or the flying machines of the dwarven kind. Several attempts would be made on the Great Realms Continent, especially by the Vectorian Kingdom in the 8th century. Inventors of steam technology and the steam engine, they attempted to make a flying vessel out of a watership (which were now using the steam engines to sail), and using a blimp filled with the rare gas helium to levitate it. This attempt was declared a failure due to the rarity of helium and weight of the steam engine system. The weight of the boilers, water and coal fuel causted the ship to be too heavy to be lifted by the helium. An airship would not be attempted again until the 12th century.
Makou Technology is the process of creating a burnable gas using the planet's lifestream, a liquid energy that flows deep within the planet. Sid Deadwillow of the Tripower Kingdom discovered that a burnable gas could be created when the liquid of the lifestream was compressed with steam, and various forms of this fuel could be created. Most common is Makou Gas used in such applications as street lamps and housing lighting. The invention of the airship would be made possible by two other forms of Makou Gas and one vital creation, the Makou Combustion Engine.
Makou Gas #2 is a lighter than air gas, which unlike the two other forms of Makou Gas is not combustable. Makou Gas #3 better known as Makou Fuel is a sludge like liquid form of regular Makou Gas (Makou Gas #1), and is used with the Makou Combustion Engine. These engines are much smaller than the Vectorian Steam Engines and produce more power. Together with the now readily available lighter-than-air Makou Gas made airships possible.
The Tripower Company is a business with no official ties with the Tripower Kingdom Government. Created by Sid Deadwillow in 1254 as a corperation, it bares the Tripower name due to its three business owners (who also happen to be the founders of the Government). The Tripower Company would regulate and maintain the Makou Reactors and sale of Makou Gas, while also creating inventions which used the technology. Its first item for sale was the Makou Airship. They would utlize and use a new industrial technique known as mass production to create these airships. This onslaught of airships would cause a major shift in the Realmism Stock Markets and Corperations as airships were faster than the commonly used Locomotives and Waterships, demand for these ships would climb, and the continent itself would change.
Airships are an everyday sight in the Great Realms and with the public sale of Makou Technology, various classes and types can be found in the air. The continent is no longer as large as it once had been, a trip from Westbridge to Figaro once took months of travel was now reduced to a seven day flight. And this was only good for a continent built on centuries of business and trade.
