Not much is known about Aster and his past. Due to his profession he spends most of his time alone. Those who do make contact with him will find he has a welcoming aura. You can't help but feel safe, seen, but also a little bit judged at times when in his presence.

Despite his warm colored coat he can come off as quite cold and hard to get to know. One can obtain an invitation to his cabin by bringing his favorite dessert: fruit tarts. Once one gets to know him they find he is a very caring and thoughtful individual; he just doesn't know how to show it.

If you look closely you can see the remnants of a more open and warm version of himself. You get the feeling that he needs the right person to come along and melt his icy exterior.
