Penelope Sieghart is the mother of Elesis and Elsword. Currently, nothing is known about her at the time. She is only mentioned in a post on the Naver blog.

Elesis Sieghart is the recent captain of the Ruby Knights and Elscud's eldest daughter. She joined the Grand Chase in hopes of finding her father after the Kanavan Trackers disappeared.
Elsword Sieghart is Elesis' younger brother. Much like his sister who makes her appearance in ELSWORD both in lore and as a character (but was initially named as Elsa), his likeness is quite similar to himself in his eponymous series. In Grand Chase, nothing much is known about him as he is only mentioned in a post on the Naver blog, and in the Sieghart family tree.
In the absence of confirmation that Grand Chase and ELSWORD takes place in the same universe or timeline, their appearances are considered distinct from one another.
