Few possess the means or the will to traverse the intangible and tempestuous Sea between the Worlds and of those who do, only the Maelgreh dare call it Home; for it is the only Home left to them. In vessels both great and small the Maelgreh have plied the Aetheric Sea's elemental waters longer then memory can tell. They say that they were the first to do so, and such is their knowledge and ability in this matter that no one of sense doubts them.
The Maelgreh are the foremost traders, merchants and explorers of Universe and their Great Black Merchant Junks are known to the ports of every World. They trade in all manner of goods, from the most exotic to the most common, collected over the course of their wanderings. Their ships and magics are also the primary means by which numerous Worlds have commerce, trade and communication with one another.
The Maelgreh themselves no longer have any World of their own. Their entire civilization has been adrift upon the Aetheric Sea for so long that the fate of their own World has long passed into shadowed Myth and Memory. Although their merchant fleets are well known across Universe, the great majority of the Maelgreh live their lives upon archipelagos of floating Islands that drift upon the surface of the Aetheric Sea. These Island Ships vary greatly in size, construction and appearance, but all of them possess the power to pass between the Worlds and float over Land, Sea, and Sky.
