Arrogance, thy name is Marivel. Pompous to the extreme, there is rarely a moment when Marivel wouldn't put on airs or talk down the rest of her party. Then again, if you're part of a highly intelligent immortal species like the Crimson Nobles, and chummy with a legendary heroine of ages past, maybe you would have some reasons to be a little on the egotistical side.
While she doesn't really see the need to prove the superiority of her Red Skills in the DL (after all, many have tried and failed to overcome her impressive array of statuses, IDs, and status protections), she does secretly adore the place. After all, it has been such a long time since she has talked to an equal such as that charming Sierra person.
