Travel

Most of Aira's lands aren't too dangerous to travel alone, so you can likely set out on foot or horseback and do just fine. If you're travelling in the Civilised East or the Farmlands, you probably don't even need much in the way of provisions as the towns are fairly close together, often within a day's walk of each other. In less populated areas however, you would need to be well prepared, or perhaps consider other methods of transport.

Caravan
On the Desert Isles or in the sparsely populated Frozen North, you would be best joining a trading caravan if you want to reach your destination in one piece, and without getting lost. If you can fight, or at least keep up with the caravan on foot or on your own mount, they may consider taking you along for free. Young or elderly passengers who amount to extra cargo however, are likely to be charged a fee for the escort.

Ship
If you need to cross the ocean, there is little in the way of passenger ships. Instead, many trade and cargo vessels tend to set aside a little space each voyage for paying passengers. If you are travelling a long way and are able and willing, your contribution to the work on board as part of the crew might be accepted as partial payment. On the other hand, if you are looking to escape the land unnoticed then your best choice is a smuggler's ship, and the price for your passage is sure to be considerably higher.
