Per the statement in the description I DO NOT own the rights to this image, or any of the paintings I did for TOR. So I cannot authorize any such use.
It's a play on the RQ covers - where a red haired warrior fights a rock lizard biting her shield. I drew her after the fight, when she tamed it.
You'd have to ask the RuneQuest people, since they came up with her for the cover.
(though even the original art mostly contains Air runes, so I'm not sure she's an Earth cultist.)
