Structure
Like other outer planes, the Abyss is spatially infinite.
In the standard third edition D&D cosmology, the first layer shares its borders with the neighboring planes of the Windswept Depths of Pandemonium and the Tarterian Depths of Carceri; travel is possible between the Abyss and these planes at certain locations. The River Styx flows through the Abyss to many other lower planes, and as such can be used to gain access to those planes.
In the Forgotten Realms cosmology the Abyss links via the Astral Plane, to Toril, the Material Plane. A number of portals directly connect it with the Barrens of Doom and Despair, Clangor, and on occasion, with, Deep Caverns and The Fated Depths. The River of Blood originates in the Abyss and flows through the lower planes, allowing travellers access to those planes by navigating the river.
In fourth edition D&D, the Abyss lies at the bottom of the Elemental Chaos.

Famous quotes containing the word structure:
“I’m a Sunday School teacher, and I’ve always known that the structure of law is founded on the Christian ethic that you shall love the Lord your God and your neighbor as yourself—a very high and perfect standard. We all know the fallibility of man, and the contentions in society, as described by Reinhold Niebuhr and many others, don’t permit us to achieve perfection.”
—Jimmy Carter (James Earl Carter, Jr.)
“There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.”
—Donald Davidson (b. 1917)
“Communism is a proposition to structure the world more reasonably, a proposition for changing the world. As such, we have to analyze it and, if we deem it reasonable, act upon it.”
—Friedrich Dürrenmatt (1921–1990)
