Arthur Laine, the Founding Emperor, lived for over a hundred years, but his reign was actually not very long.
By the time the Laine Empire was officially established, he was already in his forties, and several years had passed since he had slain the Magic Dragon.
According to historical records, during these years Arthur Laine mainly dealt with the remaining Dragon Race and the issues of the Dragon Worship Sect.
After suppressing two major counterattacks by the Dragon Race, the Dragon Race finally compromised and left the continent en masse, heading to distant overseas territories.
The Dragon Worship Sect also collapsed completely, most of the scriptures were lost, and the number of followers quickly diminished.
By the time the Laine Empire was established, there were no more dragons on the continent, nor were there any Dragon Worship Sects.
