Elscud

Elscud is the father of Elesis. He was a Kanavan Tracker, sent out by the Queen of Kanavan to hunt down Kaze'aze, but none of them ever came back from their mission.

In Ruins of the Silver Knights, Elesis claims that Jin is about as strong as Elscud.

Kaze'aze after her defeat claims that she sent Elscud along with the other Trackers into a dimension rip, and right now, are most likely screaming in the abyss. According to Lire's elders, people sent in the rip sometimes return to their original dimensions.
Kaze'aze is also intrigued after learning Elscud's name, suggesting he may have put up a fight before he disappeared in the rip.

Sieghart and Zero claims that they have met Elscud sometime before he disappeared in the dimensional rip.

Trivia

Prior to the Grand Chase Chaos update, Elscud was never referred to by name.
