Crissandre used to be a slave, working under the hot sun in the desert for years. Every day, when Crissandre went to sleep, she swore that the time would come when she would break free. And then, one day, after being punished for not following orders, it happened: Her fury exploded and turned into magical powers, which she used to summon Ymur, a Legendary sword that she used to defeat the 40 guards that were watching her and their master.
She left the place with Ymur and never came back. Now Crissandre is a respected battlemage. She intervenes in battle whenever freedom is at stake and ensures that victory lands fairly.
