Rand al'Thor, The Fires of Heaven, Rahvin, balefire, Tel'aran'rhiod
Robert Jordan has spoken...
In The Fires of Heaven, after Rand has his battle with Rahvin at the end, why is it that balefire works for his friends and not on his bites that have to be healed?
Because his injuries occurred in Tel'aran'rhiod. And what occurs there is different than what occurs in the waking world. Different rules apply.
