Grand Chase character. Leader of the Ruby Knights as well as the titular group that hunts down monsters to protect their own kingdoms from onslaught of various enemies.
The great granddaughter of Ercnard Sieghart, a legendary swordsman.
Elesis from Elsword is heavily based on Elesis Sieghart, but they are not the same character due to them having different backstories and living in different universes. Grand Chase also lists a character named Elsword as her brother but, again, this Elsword is not the same character as Elsword's eponymous hero.
