Magic circle against everyone

[Brendan]

If two casters, 10 feet away from eachother, cast the magic circle spells, one good, one evil, what would the intersecting areas be? only neutral? some sort of explosion (please)? would they cancel eachother out? what would it be?

Highly ineffective against CN, N or LN?

[Studoku]

There's nothing in the rules that say the spells interact with each other. Creatures in the area would be protected from both good and evil.

You decide. Or the DM does. The spell doesn't say anything explicitly about explosions, but if you want one, go ahead and make it happen.
