First appears in: The Death Edge
The Waller Street runoff center is a subterranean location within the Under of New San Francisco. It serves as the territory and primary base for the Haight Crew. Rylan seeks refuge here after completing an errand for Shock Crew, noting that the Haight Crew "were one of the nicer Crews in the Under, always willing to shelter a lost boy—providing he had some scratch to pay for it". As with many areas of the Under, it repurposes the city's vast, forgotten infrastructure to provide shelter for the homeless underkids who carve out an existence in the floating city.
