To the old entrance! Creeping through the dank corridor, it’s only a matter of time before you reach a slope downward. Some ways further, a low buzz signals that something is still operating… approaching closer, your eyes adjust, and you find on the wall an ancient key panel, still humming, before a pair of glass and metal double-doors. It’s dark beyond, however. The only thing keeping you company at this point, aside from yourself, is one half-dead access panel and its incessant buzzing.
