Felo'melorn, or Flamestrike in common, is an ancient Highborne runeblade borne into battle by the Sunstrider dynasty. It was once wielded by Dath'Remar Sunstrider, even before the War of the Ancients. This powerful and storied runeblade, passed down through the Sunstriders for generations, is a mighty weapon said to harness the very essence of flame.
Felo'melorn was eventually passed down to Dath'Remar's great-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 Scourge Invasion of Quel'Thalas, Anasterian wielded the sword in battle against Arthas Menethil, and grievously wounded the death knight's steed Invincible with it. Towards the end of their battle, Felo'melorn and Frostmourne clashed, but the former was severed in two on collision. Although Anasterian fought on with his broken blade, burying it deep in Arthas' thigh, he was ultimately defeated. The shattered blade was recovered and returned to Silvermoon, along with the fallen king's body, by the brothersSolanar and Falon. Later, Kael'thas Sunstrider, last of the Sunstrider line, had Felo'melorn reforged, "with magic, hatred, and a burning need for 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 byIllidan 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.
