Felo'melorn

Felo'melorn, Flamestrike in Common, is an ancient Highborne runeblade once wielded by Dath'remar Sunstrider, even before the War of the Ancients. Felo'melorn was eventually passed down to Dath'Remar's grandson, Anasterian Sunstrider, who wielded it against the Amani trolls after the founding of Quel'Thalas. It was said that Felo'melorn had spilled enough Amani blood to brim the walls of Zul'Aman. During the Third War, Anasterian wielded the sword in battle against Arthas Menethil, but Frostmourne severed the blade and he was defeated. Later, Kael'thas Sunstrider, last of the Sunstrider line, recovered it and had it reforged, "with magic, hatred and a burning need of revenge."

It was last seen when Arthas engaged Kael in a duel during the final battle between the Lich King's Scourge led by Arthas Menethil, and Kil'jaeden's agents led by Illidan Stormrage. Kael boasted that unlike human blades, which weakened when repaired, elven blades grew stronger when remade; this proved true, much to Arthas's surprise, when the runeblade was able to parry Frostmourne without failing. Though Kael ultimately fled, the sword was lost there.
