Varscona

Varscona is an enchanted longsword found in the game Baldur's Gate. It was once one of a type of sword used by Sharran priests during the sacrificial rites of the Feast of the Moon ceremonies. It was placed within the chest of its ritually mummified owner, who was to be exhumed and born again in some new form. The tomb was forgotten, however, and she was never let out of it, leaving her to develop a rage that bordered on insanity, imbuing the sword with its enhanced dealiness in combat and ability to deal cold damage. When the tomb was later discovered, only the sword was found within.

In the game, the sword is carried by the bounty hunter Greywolf, who can be encountered near the Nashkel mines if the player chooses to protect Prism from him. It's a particularly powerful weapon to be found so early in the game.
