A massive company that handles most of Terrata's mail delivery. Aeris is mostly known for its band of mages using Wind Magic to sprint at superhuman speeds across the land to hand-deliver letters and small parcels. For larger packages, they have their own special wagons that use wind Crystals to hover a few inches in the air, where they can be pushed around with little effort.

At least one mailbox can be found in just about every town and village across Terrata. Aeris couriers regularly stop by to pick up mail, although they don't hit the smaller areas every day.
