Not using the Book of Good to open the portal was just an option, this time it was the right one. In a situation where they are cornered by people in black robes. Lucas uses the Book of Good to open a portal that takes them to the next location in just five minutes.
They have arrived in the town of Cool River. The name alone is very beautiful, this town has the beauty of a very long river that crosses three large cities and several small towns, making it a tourist spot as well as transportation for residents from other cities.
It's a shame that such a beautiful city is in the middle of a conflict. Cool River City was part of the property of the House of White Horse. Lucas never visited Cool River City, the bloody historical conflict between the Granville family and the House of White Horse left a deep impression. It would invite hatred from the townspeople if a crown prince were in a place like this.
