"Farewell to Princess Melia, the group set off upstream along a tributary of the Roen River. This part of the journey was somewhat easier; although it required some climbing, there were not many obstacles in the way. Luo'er estimated that it would take about ten days to reach the upper reaches of the tributary."
"The upper stream of the tributary is situated at the easternmost end of the Northern Domain Mountain Range. Most rivers within the territory of Odelanqi originate from this mountain range. This massive east-west mountain range blocks the cold currents from the north, keeping the cold and the snow to the north side of the mountains, a crucial pillar for the civilization of Odelanqi to flourish."
"Departing from this tributary marked the beginning of their journey into Masya's territory, yet the Masya Kingdom's focus was presently southward on the problem of the rebellion, leaving them no time to care for the northwest."
