While walking nearby Alcaire Castle the Vestige will come upon a Weather-Beaten Trunk and after opening it, they will find that the ol container has preserved the tattered remnants of a knight's garb, along with a journal and a crude map leading to a series of caves.
Following the map will lead the Vestige to a large cave nearby, and in the entrance a spirit is standing like he is waiting for someone. Talking to the spirit of Sir Edain, a former Knight of the Flame, will reveal how he ended up in the cave and he asks them to help in putting the spirits of The Three to rest as they threaten the land. He'll explain the procedure and encourage the Vestige to take his steel sword to aid in the quest to entrap the souls of The Three. Defeating the spirits will bind their souls to its steel.
The Three spirits are in three different places in the cave. After taking the former knight's sword they will find them further down and by activating the rocky tomb of each of the spirit's, they will appear to the Vestige. When all three are defeated and binded into the steelsword, they must proceed further down into the depth of the cave, to the big fissure.
The souls of The Three are seen in the large fissure, upon arrival. They are not very happy with the outcome but after throwing the sword into the fissure will make them disappear forever. When talking to Sir Edain afterwards, he has sensed a change a serenity is now flowing into his spirit. He is released from the plane he was in and before leaving, he sends the Vestige to the surface with his gratitude.
