Gwendelline

Gwendeline is Alexandrea's younger sister who was captured by the Queen of evil, Zephiria, her being the one who hid the crystals for protection which Zephiria solely wanted to get her hands on for the power of being able to create a world of darkness and kill off all light and good. No-one really knows much about Gwendelline apart from her being Alexandrea's sister that they are going to rescue, though Felix and Chii knew her well they haven't told the others much about her and what she looked like.

Appearance
Gwendelline hasn't made an appearance up until now so most of everyone doesn't know what she looks like apart from her sister, Alexandrea, friends Felix and Chii as well as others who've known her even before she was captured by Zephiria and disappeared.
