Timbre takes the lock of hair from Shaylir. Timbre's flames don't harm the hair, and it stands out as the single item you've seen in days that's been untouched by heat and fire. She holds the lock in both hands and looks at it, standing immobile. Flames flicker around you. The burning forest pops and crackles.
After an indeterminate amount of time Timbre drops to one knee and looks at Shaylir. Her face has softened. "Innenotdar and the seela are bound to me," she says to Shaylir. "As long as I live, they will live. There is nothing left that can save the forest now. The same creature that keeps the forest from fully dying also keeps the fires from burning out. If it is freed from the bottom of the lake everything dies. Including me.
"There is one other possibility. The living blade I gave to Anyariel. It is part of me, and if it survives then so will Innenotdar. It was bonded to Anyariel, and that bond kept the blade alive while she lived. Now, like the rest of the forest, it's kept alive by that creature. If someone draws that blade from the creature they can choose to bond with it, like Anyariel did. That will keep the blade alive as long as they live, and if the blade lives, Innenotdar will live.
"That is the most I can do to help you and your friends, halfling. Please kill that creature."
