These airships have no internal frame. The internal pressure of the lifting gas (non-flammable helium) and air-filled ballonet bags maintain the shape of the envelope.
The only solid structural parts are external:
the passenger cart, the nose battens (hollow aluminum tubes at the nose of the Blimp) and the tail fins.

These airships have a solid light-weigth frame. The aircraft is designed for aerodynamic efficiency, and have a mechanical engine that powers and propale the aircraft.

These airships can have any frame or design. the elivation and propellend is determind by the magical crystals.
the price of these vessels is determents per magical crystal.
Vessels that use magical crystals are not limited or hampered by altitude. only by the comfort of the occupents.

the amount of crystals depends on the size of the vessel:
1 crystal is needed for a large or smaller vessel.
2 crystals are needed for a huge vessel.
3 crystals are needed for a massive vessel.
4 crystals are needed for a enormus vessel.
6 crystals are needed for a colosal vessel.
8 crystals are needed for a gargantuan vessel.
10 crystals are needed for a titanic vessel.

These airships are magically enchanted. each permanten casting on a vessel is determent by the following:
Each enchantment cost 10.000 C.C. per spell Grade, doubled each size catogory greater than Medium.

Examples are:

Feather fall 200.000 C.C. doubled each size catogory greater than Medium.
Levitation 300.000 C.C. doubled each size catogory greater than Medium.
Immovable object 300.000 C.C. doubled each size catogory greater than Medium (can be toggled on and off).
Wall Walker 300.000 C.C. doubled each size catogory greater than Medium (prevents crew falling of the vessel).
Awakening 600.000 C.C. doubled each size catogory greater than Medium.
Fly 600.000 C.C. doubled each size catogory greater than Medium (this will grant the magical flying speed).
Stronghold 700.00 C.C. doubled each size catogory greater than Medium.
Invulnerability 900.000 C.C. doubled each size catogory greater than Medium.

A locomotive is a specialized type of train cart which is used to run the whole train.
The locomotive is self-propelled, generating energy through the burning of fuel, the use of electricity, magnetic levitation, or other methods.
Locomotives can be used to either push or pull train cars.
