Airships are commonplace on Cerillith. The continent of Esdar is no different and the Republic and Holy Lands in particular Airships are often used. The most common purpose of an airship is as a military vessel, however with countries like Aellith Terrellia where money can buy anything Airships find more mundane uses such as luxury vessels and freighters.

The Skies over Four Winds

A scene over the skies of Four Winds as the Republic Fleet mobilizes for an assault on Acersi, this historic battle took place over the mountain range that seperates the two nations. In this picture one can see several crusiers (at the top) several frigates (foreground and top) and in the background the Dreadnaught King's Bounty.

In Mellornia an Airship is classified by it's size and purpose:

The Smallest Airships that still qualify to be airships and not Flyers are smaller squad sized Zeppelin type vessels. Not carrying more than around 12 men a Frigate serves as scouts, picket ships, and escorts in airship battles. Frigates are charged with screening cruisers attempting to eliminate cruisers maneuvering to boarding range. By far the most abundant type of Airship, they are also the lightest armed, least durable, and generally the fastest, however their speed isn't always assured as the parties Intruder 1 is actually slow by Frigate standards. Aelleth Terrelian Luxury Airships would fall into this category, but are never equipped for war. They generally feature a large observation deck for sight seeing.

The Bread and butter of the aerial battleground. Airships that fall into this category serve to carry the flag in battle. They are decently armed, carry boarding parties and flyers, and can withstand even the most devestating magical onslaughts that a spellcaster could manage. In battle they slug it out with other cruisers providing cover to any dreadnaughts in the area in the same fashion as frigates do for them. The largest Aelleth Terrelian Frieghters could be classified as Cruisers however they would perform poorly in any other capacity than carrying cargo. Frieghters are generally very open in the gondola.

Massive, unbelievable huge airships armed to the teeth with various armaments including ballistas, catapults, and the like. They generally house squadrons of flyers, but are far too slow to carry boarding parties. Dreadnaughts are generally crewed by hundreds and use massive constructs enchanted with flight magics to keep the aloft. Even with such technologies Dreadnaughts creep across the sky at a speed of barely 2 mph, slower than a human can walk. History only records a handful of Dreadnaughts ever reaching active service and several more that were too impractical or incapable of flight. Those that did reach active duty were legends of their time. Pictured above, the King's Bounty was "sunk" in the battle over those mountains but not before devasting the Acersian defenses dotting the mountain range and "sinking" the Acersi Dreadnaught Kamikazi no Amaratesu. along with several cruisers. Currently only two Dreadnaughts are in active service in the Mellornian region and neither the Republic or Holy Lands was willing to commit them to battle during this most recent war.

Parts of the Airship

Pictured above is a common cruiser design. The major sections of the ship are numbered and explained below.
1.) Lookout Post - A small compartment which provides a greater degree of freedom in looking around the craft.
2.) Tenser Engines - These powerful Rotors were designed by the wizard Tenser. They use basic principles of a levitation spell to provide enough lift to allow the craft to leave the ground. These particular engines are more mechanical in design and could just as likely be animated to rotate at great speed. Larger craft rely more on the principles of the Tenser Engine.
3.) Tenser Engine - Another Tenser engine, this engine provides forward momentum.
4.) Attitude Fins - These can be angled left, right, up, and down. They are used to turn the craft and change elevation.
5.) Crew Compartment - This lower portion is hollow and used for cargo, crew, and control compartments.
6.) Observation Deck - This deck is an open platform. Boarding Parties use it in much the same way the deck of a sea vessel would. It can also mount weaponry.
7.) Armored Gas Bags - Mythril plating covers these gas bags. While they don't contain enough gas to lift the heavy craft, they do aid in slowing the decent should a Tenser Engine fail or be destroyed. It's just as likely that a ship uses soarwood panels instead of mythril, it's an issue of cost to function.
8.) Armored Hull - Unlike Zeppelins, this area of the ship is open and can be used in much the same way as a crew compartment. Some variants of this ship have firing points built into this section. Cannons can be placed inside to function as batteries.
