I should say first that I haven’t read it. Also this may have been covered in other thread that I missed but it just came to me and thought to ask everyone.

My question, how come Graendal’s Gateway weave isn’t destroyed by Rand’s Balefire? Shouldn't the weave have been wiped out, thus never opening in the first place, or do the temporal properties of Balefire only work on non-power things?
