Ork Underground refers to what was known as Seattle Underground. A network of underground passageways and basements that was ground level at the city's origin in the mid 19th century, these spaces eventually fell into disuse as the streets were elevated, becoming forgotten basements and occasional tourist attractions. This trend continued till the Night of Rage of 2039, after which the Underground became a refuge of city's metahumans. The Underground is known for poor Matrix reception.
