Deciding on Mjolna's background was difficult. Seeing as how most of the fandom saw her as the mare version of Thor. While others saw her as an alcoholic blacksmith. Then I decided why not make her a regular pony with a hammer who is the only Earth Pony to walk with pegasi in the clouds and have the ability to make storms when she wants. The ability to sense danger came to me when I began writing Pinkie's same ability the second time. But also have a history with Applejack.
