Pride goes before a fall, a haughty spirit before destruction. Shaston has fallen but that's all in the past. She has had a lot of Origin cycles to regret her decision so she doesn't feel much now. She only wants to pass on her legacy before she dies.
She believed that anyone who has any hope of succeeding where she failed must have a transcendent talent for all the six laws that made up her concept. The difficulty of possessing 6 talents aside, the talents will also have to be in earth, fire, water, air, light, and darkness. A single one missing out of these six will render the combination lacking.
