Thaumatic Lattice Engine

The Thaumatic Lattice Engine, also called TLE or thaum engine for short, is a kind of engine used in a large variety of high-speed land vehicles, such as Thaumcycles, but also full Skyships. The mechanisms which allow the pilot to steer and control their speed are quite complex, but the underlying motor, the engine itself is quite simple. It is really not much more than a large crystal cut in a certain shape that binds specific Sthrena. The most efficient kind of Sthrena to use in an engine are fiends of various kinds, typically between one and three are used in one engine. Should the crystal be cracked, there is a strong possibility of these fiends escaping into the material. They should be eliminated as quickly as possible, as loose fiends can be quite troublesome. On the bright side, they are usually very weak due to their captivity in the engine. However, as is the case with all Sthrena, they should never be underestimated. The engine used physical Asa as fuel, that is, the fiend consumes the Asa and is compelled to generate kinetic energy from it. This is a lot more efficient than using a Spellbinding Device for instance, due to the greater efficacy in channeling exhibit, and their crystalline prison further amplifies the singular conversion they must make.
The Thaum Engine is primarily used in Zemaran, and vehicles containing them are almost exclusively manufactured in Zemeran Territory.
