    Summary

    The streets were quiet in the Under-City, as it was still barely dawn. The slowly brightening sky casted wisps of oranges and pinks over the cobblestones, and stained the window panes of the sleepy town, a telltale sign of the quickly approaching sunrise. At first, this sight would appear quite serene, maybe even tranquil to the ignorant outsider, or the casual passerby. Frisk new better,however, then to trust the peaceful illusion presented by the empty streets of the Under- City as she stuck to the shadows of the back alley ways, refusing to so much as touch the light of the new dawn. This was Ebbot after all, and no amount of peaceful sunrises could bathe away the true grime of the Under- City that existed in the form of organized crime and corruption which clung to Ebbot like thick black tar. Though it might look pretty from a distance life was hard here, and making an honest living was a concept really only found in fairy tales.
