Hmm... good question.

While most magical effects stop when the caster is knocked out, it isn't always like that.

But the more interesting question to me is, if the land will be restored to it's original shape and size if Irene is knocked out. Hisui could be restored by another mage (probably Wendy), but I don't see anyone else being able to restore the entire peninsular other than Irene herself.
