[Is this the kind of stuff you are looking for?]
The plains witch has been studying the stolen flame , trying to figure out how to make fire herself, but has been unable to do so. She has prayed had played to her gods in the heavens, but nothing. Still, one morning, after spending almost her entire night in such prayer, she notes a pattern in the stars, and knows that it means something. She even knows what the constellation was meant to be called. She carefully paints its shape into a piece of tanned hide, and then speaks the name of the constallation. The paint vanishes from from the hide, but the her talisman begins to glow, and the area around her is bathed in light.
Now, each day, she meditates briefly on the constellation just before dawn. The has also found that several of her other spells have analogous constellations, and that thoe symbols can also be painted onto hide. She has not done so very much, yet, because she feels drained by the action, and the paints needed for the ritual are precious. Still, the charms she has created may be of use in the coming battle.
