Skies of Legacy
Legacy Range is the mountain range that separates every country. The towering mountains reach unbelievable heights, making travel through them impossible except by airship. Legend has it that the Humans of Old created the Legacy range with their powerful weapons in a huge battle, though there is no evidence for it. It is also rumored that strange and powerful beasts live deep within the mountains, but nobody has been far enough and survived to confirm this. The countries has little contact with each other prior to the invention of airships, and nobody dared cross the mountains.
