Gracesiki Mountains

The Gracesiki Mountains is a dangerous mountain range north of Moby, this mountain range holds the Marigold Fortress as the mountains act as a strong primary defense barrier against ground force assaults, these mountains are very hard to travel along due to sudden drops and sharp rocky terrains, not even vehicles can travel through without some form of obsticals getting in the way, the Quantonian Empire took the harsh terrain of Gracesiki to build Marigold Fortress for the Kingdom of Moby. 
The Gracesiki Mountains mostly in the winter gives off a blueish hue due to the way the lighting hits the frost that covers the range, the mountains are not cold enough to give off snow but are cold enough to give off frost and frozen rivers and lakes.
There is a road which cuts right through from Marigold Fortress to to Teripi City, however this road is heavily restricted and has bunkers, guard towers and checkpoints along the way, mainly due to the fact that Marigold Fortress is the most protected military installation in Moby.
