Sogelius is the head of the Divine Dragon Elders. He has earned the title of the strongest Divine Dragon alive.
...little is known besides that he battled with the other drath against the humans in a battle that ultimately split the continent into two, the drath continent and the human continent...
Sogelius informs Gerosin that after Krotosen's attack, the people were petrified, and so he disguised all of the darkness in the surface world with The Clouds. Sogelius runs away from Shrow'd's genocide of the Divine Dragon Realm with the other Divine Dragon Elders. His location is unknown for the remainder of the chapter.
