As far as using opposeing runes ,I think that going to be a cult to cult thing. For those that have previous version of Runequest should remember certian cults prohibited its members from casting certian battle magic spells. Like light cults could not cast darknesswalll ect. But then some darkness cult could cast light spells cause their God defeated certian fire/light Gods and stole their runes.
and as for what happens to the rune after you master it. I was thinking in my game it becomes like a tattoo on the body, at least in some cultures. It been mention certian creature like dragonewts do tatoo runes on their body but thats one idea.
