DESCRIPTION

This +5 drow bane holy huntsman keen elven war blade is an ancient artifact from the Elf-kin War and was wielded by Narnel, a renowed king of the elven kingdom of Eushonéva. Crafted by powerful clerics and blessed by divine investiture, the sword became a symbol of the surface elves' victory over their corrupt kin, the drow.

Originally named Anánduil, the sword quickly came to be called Soulsinger, which has come to be its preferred name. Following the war, the sword was passed from father to son through the royal lineage of kings and hung in a place of honor in the throne room above the seat of rulership. There it stayed ifor many centuries, to serve as a reminder to the elven people of the treachery of their dark elven brothers.

Unfortunately, the sword mysteriously disappeared from its appointed resting place over 2,000 years ago and was lost from the world for many centuries. However, whether by chance or divine design, it was recovered by the powerful elven hero Aragast Anadriel, from within a magical vault located deep within the untamed regions of the everdark.

Soulsinger is forged from elven whitesteel and etched with elven runes of holy power. Drow (and drow only) who come within 60 feet of this blade, whether they are invisible, ethereal, hidden, disguised, or the like, causes the weapon to vibrate, alerting the wielder to their presence and general direction in which they can be found, much like a rod of enemy detection. Soulsinger is well known in the verbal history of the drow, and the mere mention of its name has been known to cause fear in the hearts of even the most hardened drow warriors. As such, it was forged for the explicit purpose of slaying drow, and if it strikes such a creature on a critical hit, the target must make a DC 25 Fortitude save or take 50 points of damage, much like an arrow of slaying
