the three Witches

In a clearing in the forest, you observe three women standing around a fire. A cauldron hangs above the fire on a tripod. They chant strange words and move to the rhythm. Finally, one of the women takes the cauldron from the fire and pours each a cup. The women drink the potion, then raise the cups and call out together. "Hecate!" You are about to retreat when they notice you.
