She's Scandineighvian, coming to Ponyville from northwestern Equestria, and speaks with a Swedish accent. She's named after Thor's hammer, and herself is gifted with a talent of blacksmithing, making hammers and axes very sturdy and reliable. If you need a hammer in Ponyville, ask Mjölna for it.
Don't get on this mare's bad side, she's an ancestor of pony vikings and their powers can slip into her when she's angry. You wouldn't want to get stomped while she rants in a booming voice about how her ancestors were doing the same while drowning themselves in cider.
Really, it would be very, very beneficial for you to have this pony as your friend and ally. She's very strong in both strength and will, highly loyal, hard-working and kind. Her coat is fine, and she smells like fir woods and daffodils.
