Wall of Fire and Stinking Cloud

[Lord Orion]

Is there any rule that says these two spells can't be active in the same area? As in, "The wall if fire will burn away the stinking cloud" in any square they are both active in. Or some such. I have never encountered any rule like that.

[Elamdri]

I don't see anything in the text to suggest that the two are incompatible.

[King of Vrock]

Unless the spell specifically state an interaction, or it violates a general rule in the magic chapter two spell effects can occupy the same area and are completely independant of each other.
