Lower City Streets

You break off into a sprint, turning corners sharply and scampering down random alleys. You try to be as unpredictable as possible. You make distance on the shadowed figure, but every time you think you've lost them, you catch a glimpse of them turning a corner. This is no inexperienced tracker. 

After what feels like hours of running, you find the wall of the Upper City. The Lower City has begun to climb it like a vine, with buildings stacking upwards. Ahead, you see a large sewer drain pipe jutting out of the wall. The door is easily large enough to fit you.
