Ladder: Runner

With unmatched physical discipline, she has perfected a body designed for raw speed and agility. She is not a born soldier. She broke records in the dash and ran for hours in marathons while others fell exhausted by the roadside. This was still not enough, and she soon began finding more challenging ways to get from point A to point B. walls, jumping across roofs, sliding under cars--nothing stood in her way. It’s not enough just to be athletic. She has to keep her eyes and mind sharp, to gauge distances, crawlspaces, and the shortest possible route even if it involves some death-defying feat of acrobatic skill. She can keep an entire landscape in mind, analyzing paths and routes of escape, even when everyone else just sees walls. This may not be raw brainpower but a natural instinct of the surrounding environment. In her spare time, she runs.
