In Lady of the Trilliam, the last remaining princess of the Trillium, Haramis, must seek out a successor to wear the mantle of the Archmage. The most likley candidate is a young woman every bit as recalcitrant as Haramis was herself.

Millennia later, the balance of nature is just beginning to recover from all that magic gone awry...until an unknown evil stirs...and severe earthquakes, widespread volcanic eruptions, and disastrous weather rock the land once more. Only the legendary Sky Trillium can heal the ancient wounds of the world. The Sky Trillium is made from the three talismans of the princesses Kadiya, Anigel, and Haramis - but Anigel is missing, and Kadiya's talisman has lost its potency. What's more, someone else - someone with evil magic of his own - is after the three talismans for himself. If he succeeds in his plan, then the world will surely be destroyed. But even if the three sisters are able to regain all three of their talismans, will they be strong enough to control the awesome magic of the Sky Trillium? less
