As for Fevocius, he was an adventurer in a large city. In a very short amount of time, he was able to raise his rank and became a veteran in the adventuring business. That smooth selling road gave him extra confidence or rather over-confidence and he became an arrogant prick.
But his arrogance ended when a higher ranking adventurer beat him up and took his girlfriend before his eyes. For powerful beastkin there was a custom of betting their lovers or wives for a duel and Fevocius did just that. And then he lost measurably and was forced to lose both his pride and his girl.
After this humiliation, he was unable to live in the large city and also could not continue working as an adventurer. Wherever he went, he was made fun of. So he had no other choice but to run away. Now he did not want to be anywhere near a person stronger than him. So he decided to go to one of the less powerful nations where he could be the strongest with his powers.
Most of the people did not go to those nations as they would not be able to increase their powers anymore there. But Fevocius was fine with it. He had noticed that he had suddenly stopped growing in strength after he became a veteran adventurer. That was also one of the reasons why he was always so angry. He understood that somehow he had reached his growth limit.
In this situation the only thing that gave him any kind of peace was the praises about his past achievements. So when people tried to deny him that he became angry and lost everything.
...
But after going to a backwater nation he was able to find that fulfillment again. Here he was the strongest person so everyone was always praising him. That boosted his confidence and he slowly gained his confidence back.
After a few years he became the most famous and most infamous person in that nation. Famous because he was extremely powerful and no one living in their nation was able to defeat him. And he was infamous because he had ruined many girls' lives.
According to Maggy, this city has a separate dimension in the very middle. That dimension was named "Tidur of Eternal Rest". According to Maggy, the person who was able to fight her, an ancient dragon to a draw was fighting to protect something and Rein had found all these to be quite interesting. So he was looking forward to learning more about it.
After teleporting to the City of Night, Zoa, the Conquerors found themselves in front of a super large door that was the entrance to the city. This door was very majestic and it was giving off an intimidating feeling. If it was anyone below the rank of a transcendental person, then that person would not be able to move after seeing this imposing door, let alone entering the city.
But for Rein and his group it was not a big deal and went toward the door. Then Rein pushed the door with a little bit of force and surprisingly the door slid open very smoothly. Rein had expected something like a guard to attack them at the door but that did not happen and there was no one at the gate.
After entering the city, they found out that the city was almost empty. With a normal glance Rein's group was unable to see anyone. Then Stella used her Eye of Clairvoyance to look at the whole city with a single glance. This city was quite big, but nowhere as big as the Yueming Wasteland. So Stella was able to take a look at the whole city with her ability.
To her surprise she found that there were only a few buildings that had monsters in it. According to Maggy, there should have been two types of enemy in this city. Evil devil looking monsters and powerful undeads. Especially their should have been many undeads roaming around the city. But surprisingly Stella was unable to find any undeads here.
The only enemies present were the evil devil looking monsters and even their numbers were on the lower side. There was definitely something wrong with this city.
As the monsters were weaker than expected, this did not weaken Rein and his lovers caution. Instead they became more cautious. They were not fearful about their lives. With Rein and Anna it would be almost impossible for them to die but still unknown were always to be respected.
With that in mind, Rein and his lovers went toward the monster that was closest to them. They did not split up and went to face it together for the time being when the situation was unclear.
