Indomitability

A draconic face shaped of fire, its head adorned with a massive crown of jagged horns, appeared within a wall of flame and called itself Indomitability. It claimed to be prisoner in the Innenotdar Fire Forest and asked for the party to free them from the prison of this enforced flesh. It told them to follow the river to the singing lake where it lies trapped beneath its surface. By ending the song of the deep, the song of agony and eternal vigil, silencing the forty tongues that hold it there, the party could free it and gain its boon.
Jack used the wand to attempt to dispel magic on the wall and it disappeared.
The party continued to learn about Indomitability as they traveled through the forest. Years prior, Indomitability came to the forest in the form of a giant stag, ravaging the woods and the people therein. It was pinned to the bottom of Seela Lake by Anyariel, who wielded a greatsword hewn from the living wood of the First Tree and granted to the elven woman by Timbre. To keep Indomitability pinned, the Seela have held vigil, singing the Song of Forms, which forces him to stay in his stag form.
