Torak wields Cthrek Goru at Cthol Mishrak

Cthrek Goru, the Dark Sword of Shadows wielded by Torak as the counter to The Sword of the Rivan King. It appears to be able to control the powers of Darkness and was retrieved later in the Mallorean and wielded by the Demon Lord Mordja and used to kill one of Belgarion's Companions, the Silent Man—the mute Toth.
