Nedrehiem and Loptheim

I'll write an introduction page later.
Yes, I am incredibly lazy. Short version: I give you a new fantasy world (hopefully) every day.
They won't be that detailed, because I am creating them completely on the spot, but hopefully you enjoy them anyway.
Anyway, let's go!:
Long ago, there was a war between the gods. And in their war, the world was split in two. And one world rose, so that its sky almost touched the heavens, and the other sank, until it rested upon the roots of the world. The upper, Loptheim, is bathed in gentle sunlight. It is a land of prosperity, and very uch a traditional fantasy world with kings and knights and elves and wizards. But the lower, Nedrehiem, is bathed in gloom. The people are barely able to grow crops. Poverty is rife, and violence common. Even magic is weak there. But because of this, they have developed a more 'modern' society - governments are focused on trying to help the common people, and technological development has been faster.
The two worlds are connected only by a single bridge, which is steep, narrow, miles long, and guarded at both ends by an order of knights who believe that, should the bridge fall and the worlds be entirely severed from each other, Nedrehiem will fall utterly into darkness. To prevent any risk to the bridge, travel between the worlds is highly regulated, though individuals known to the bridgekeepers can generally pass without issue. This policy has made the occasional efforts of Loptheim's monarchs to aid the people of Nedrehiem somewhat ineffective.
