Summer of Lore #25: The Rainbow Orb

This tale is about a legendary crystal orb known as the Rainbow Orb--a Seer's, mystic's or enchantress' dream weapon

The basic bones of the story:

An enchantress decides to seek the Rainbow Orb as a chance to avenge her mentor, who perished at the hand of a monster (what monster this is depends on the storyteller) Along the way she meets an older enchantress infamous for her tricks, and ends up falling for a few of them (what they are, again, depend on who's telling the story. When she finally gets the Rainbow Orb, she first uses it to punish the old enchantress for tricking her.
