The Chains of Phantasia

Mentioned only in passing by Lucien Novelle "The Chains of Phantasia" is the name of what apparently is some kind of magical harp. He recalled it being mentioned in discussion of Vestiges, though does not remember exactly why, or how they are related, if they are at all.
It is currently theorized by Group Alpha that the harp itself is a vestige.
They were not quite correct on the assumption of the Chains being a Vestige, however, it is related to them. In truth, the Chains of Phantasia is a powerful artifact created by the Mythic Hero Korison Brasshammer. He created it with the intention of it being an 'Ultimate Weapon of Good' to be used by Soren Hightower in case a threat like Tiamat ever rose again.
The Chains of Phantasia, alas, is not finished. The main body of the instrument has been created, sealed away and watched over by a guardian, but the strings are a more complicated matter. The strings of the the instrument are the vestiges themselves, and are what truly give the artifact power. Once all seven vestiges are purified they are then to be dispersed and forged into the strings by Korison Brasshammer.
Group Alpha, especially Lucien Novelle, is currently on the hunt to find and purify the Vestiges as to finish to Chains and wield it to finally defeat Khyber and finish the eclectic group known as the Hushed once and for all.
It is said the artifact can only be used by one who is 'Pure of Heart'.
It was recently discovered by Group Alpha that there was once another artifact that shared the name the Chains of Phantasia. A grim and haunting harp that was used to seal away the then Queen of the Hells, Phantasia herself. Phantasia has long since perished, and the original chains with strings made of unicorn hair, dismantled. Soren Hightower requested its successor be named as such because he thought that it was 'neat'.
