The Avian Monarch and the Mother Tree!

In Arcane City, Merlin was strolling alone. He thought of Arcane Wizard Setoh. Along the way, he discovered numerous Spell Casters who originated from Setoh Arcane City. 

Such as the Nightmare Lord, the Sorrow Lord, the Arctic Lord and so on, their identities were slightly awkward at the moment. Since Setoh Arcane City was destroyed, they had become nomads. 

Of course, Arcane Wizards Augustus and Ceci issued an open invitation to everyone. A large number of Spell Casters from Setoh Arcane City entered these two Arcane Cities. However, these Lords did not commit to any Arcane City. 

Merlin also thought about Old Man Etha, whom he met upon landing in Blackwater City. It was him who had led Merlin to embark on the Spell Caster journey. Then, it was Wizard Leo whom, through his Darkness Eye, allowed Merlin to escape many dangerous situations.
