The First Step

In the secret chamber of Setoh Castle, Merlin's surrounding was quiet. There was no one else but himself. Merlin gently shut his eyes, and examined the additional memory which had surfaced in his mind.

Darkness Eye was something Merlin had received when he was still weak. Once upon a time, it was his strongest ability. Even right now, the sixth form of Darkness Eye could rival a peak Great Wizard's abilities.

Nevertheless, following the advancement of Merlin's Spell Caster level as well as the improvements in his Spell Fusion, Hallucinating spell, and other abilities, the sixth form of Darkness Eye eventually lagged behind the rest of Merlin's abilities.

As for the seventh form of Darkness Eye, Merlin came to understand over time that the key to unlocking it must be controlled by the Legend of Darkness Oflas. Unless Merlin could obtain the key, he would not be able to level-up Darkness Eye anymore.
