Even the construction of a simple passageway through the Little Greenland Forest was exceedingly difficult, stretching over four hundred kilometers from Bruce Fortress to the rudimentary river dock on the banks of Lake Nissai. Although the river was relatively wide, it was bordered by untouched primeval forest, barren and uninhabited. The most troublesome aspect was the threat of magical beasts along the way. To establish a smooth connection between the river dock at Lake Nissai and Bruce Fortress, it was imperative to build intermediary supply stations along the four hundred-kilometer stretch of waterway, which posed even greater danger.
