This object was recovered from the Red Court vault inside the Bank of New Orleans. According to the records of the Red Court, it is referred to as a Fomor weapon. It appears to be a giant fossilized ammonite shell. It is about 2 feet in diameter, and weighs 300 lbs. It is unclear what it does, or even if it is really anything more than a fossil that belongs in a museum.
The object is currently being stored by Rikard Baldurson in the Plaza Tower under the “watchful eye” of Monoc Securities.

After being triggered mysteriously, the weapon began to float and spin—and seemed to be creating quickly intensifing tropical storm in the Gulf of Mexico. Fortunately the Bourbon Street Irregulars took it upon themselves to find a way to destroy the weapon—eventually throwing it into the maw of a Kraken.
