Magic Circle against Chaos was an abjuration spell that created a sphere of warding against mental and physical attacks from chaotic creatures.
This spell operated just like magic circle against evil except that it extended the area of effect for protection from chaos rather than protection from evil, and it could trap a nonlawful summoned creature.
See the description of the components at magic circle against evil.
