The post office is responsible for the delivery of letters. Most cities have a post office available for adventurers to use.
Once in a post office, an adventurer would request a letter. The letter may only be written upon and mailed once. In addition to literary messages, one may choose to place a few items into the letter to be mailed to the recipient as well. In most post offices, when the letter is ready to be mailed, the post office attendant will take the letter and attach it to the leg of a dove. The dove will then fly about the skies until the recipient is located when, on cue, it will deposit the letter into the hands of its target.
The cities of Shallam and Mhaldor are the exceptions to this manner of delivery. Letters mailed from the city of Shallam are delivered by colourful paradise birds while ones mailed from Mhaldor are transported via cross little gremlins.
