Marivel is the last of the Crimson Nobles after the entity known as Lord Blazer slew her family and the rest of her brethren. She assisted the Sword Magess and Luceid in defeating Lord Blazer but since then has been traveling the world in order to prepare and prevent ... something. Marivel is an incredible engineer who employs both lost knowledge and modern techniques into her work and works as an ARMS Meister who is both picky about whom she works for and strange about the payments she asks for. She is connected to the Valeria household as far back as anyone can remember. She often comes across as snooty and frankly more than a bit arrogant but behind it all is someone who deeply cares about Filgaia. ...Or so she says, anyway. Strangely as of late she has picked up her activities but if she's trying to prevent another worldwide disaster...one might wonder why she is being so tight-lipped.
