The flying vessel looked much like a normal seagoing sailing ship. Typically, they had three masts, square sails, and a broad flat beam. Giant sea turtle shells were often used as armor.
The original creation of skyships dated back to Netheril and were a secret of Halruaa for centuries. However, in the early 1370s DR, a renegade wizard spread the secret of Halruaan skyships to others.
Although a rare and genius invention, a Halruaan skyship was no more than an expensive magical item. If a spellcaster was proficient with the required magical knowledge and able to find the materials, creating one only took a matter of months. Crafting such an item required:
- Knowledge of how to craft magical items;
- Knowledge of the fly and suspension spells; and
- 400,000 gold pieces worth of materials, including a ship vessel.
