Denvel's True Agenda

There are four Void Sigils: one in the Dragonclaw Ruins, one in Minsterhorn, one in the Monument Statue of the Hero,
and the last one is set within Asterleeds.
The goal of Denvel, the leader of the Dark Mist Legion, is to use the Void Sigils to engulf the entire plain to achieve his revenge.
The only way to undo this is to find a large amount of Engram to neutralize the Void Mist within the sigils, thereby dismantling Void Sigil.
